Information about “XY-SOLVE”
Teachers will welcome this computer-aided instructional system for the
design of tests and exercises for high school and college level
Algebra, Geometry and Trigonometry.
XY-Solve challenges the student to solve a puzzle consisting of
mathematical functions. Each piece of the puzzle represents a graphic
solution to a standard formula. Puzzle complexity may be varied from
simple displays of individual points or lines to extremely complex
combinations of quadratics, trigonometrics, parametrics, and composite
functions.
The student's progress in solving each piece of the formula is
displayed and special help is available for identifying boundaries and
zeroing in on solutions. A function teachers will appreciate is the
performance reporting module which tracks the number of solution
attempts by the student, and difficulty levels reached.
XY-SOLVE has seventeen "puzzle files" and the instructor can formulate
additional problems by using the macro facility. Other system features
include moving window displays, function-sensitive statistics, and
context-sensitive help screens. Data can be imported in a variety of
formats. Selectable sound and color options add impact to the lessons.

XYSolve Sample Session
======================
Backing Up Your Diskettes:
Diskettes can be damaged or lost. We recommend that
before you use XYSolve, you make a copy of the Master
Diskette. Use the copy whenever you run the program, leaving
the Master Diskette in a safe place so it can be used to
restore your copy should it become necessary. Specific
information on making backup copies of disks can be found in
your DOS (Disk Operating System) manuals.
Caring For Your Diskettes:
Handle diskettes carefully. Treat them as you would any
valuable object; for, with your files on them, that's exactly
what they are.
Diskettes should be stored in an upright position in
their protective sleeves. They should not be subjected to
direct sunlight, magnetic fields (Vacuum cleaners,
televisions, microwave ovens etc.), dust, or extreme
temperatures.
When you handle a diskette, try not to touch the
magnetic media. Don't bend them or write on them with
anything heavier than a felt tip pen.
The XYSolve Program Disk:
All of the programs and files used by the XYSolve system
reside on a single disk. The XYSolve program itself consumes
approximately a third of the available disk space. The
remainder of the disk contains the installation program and
the practice Puzzle files. Sufficient disk space remains for
several of your own Puzzle files. Should more space be
needed, we recommend deleting the installation and practice
files as well as any user developed Puzzle files that are not
immediately needed.
Page 3
Before We Start:
XYSolve does a lot of exciting things with disk files.
To help it do its job efficiently, you should reserve as much
file capability as possible in your computer system. You do
this by adding the statement "FILES=20" to what is known as a
CONFIG.SYS file on your boot or system disk the first time
you use XYSolve. If you have experience in preparing files,
but are a little rusty, you can find refresher information in
your DOS (Disk Operating System) manuals. If, however,
you're not sure what we are talking about, an easier way has
been provided to get the job done. A special program called
"INSTALL" has been included on your XYSolve master diskette.
All you have to do to make or alter a CONFIG.SYS file is to
enter the name INSTALL just as you would any other program
you wish to run. After INSTALL finishes, you should REBOOT
or RESET your computer to enable your operating system to use
the instructions you have just prepared.
First Steps:
Starting the program is simple, merely insert the
XYSolve master diskette into your disk drive and enter
XYSolve at the DOS A> prompt. In addition to XYSolve itself,
your master diskette contains several auxiliary files and
programs such as INSTALL. The auxiliary files are practice
Puzzles. The Puzzle files contain the sequences of
instructions that comprise the individual pieces of each
puzzle. (more on this later) These auxiliary files are
there to help you become familiar with all the interesting
capabilities of your new program.
Conventions:
Before we can go any further, we need to establish some
conventions to help us as we progress. The first concerns
keys. When a keypress is called for, the indicated key will
be written within brackets like this: <KEY TO PRESS>.
In addition, menu selections and commands will be placed
within single quotes like this: 'MENU SELECTION'.
Page 4
Important Keys:
ARROW (CURSOR CONTROL) KEY..
Indicates MENU selections.
Positions the PLOT CURSOR.
ENTER Key..
Selects MENU levels.
Executes FUNCTION selected.
Indicates ACCEPTANCE of plot values.
ESCape Key..
EXITS from menu levels, plot options, and math
function modules.
REJECTS unwanted plot parameter values.
NUMERIC Keys..
ENTER plot parameter values.
Just remember, SELECT with an <ARROW>; ENTER with
<ENTER>; DEFINE your plot value with a <NUMERIC>; and EXIT
with <ESCape>...Its that simple!
Grand Tour:
After XYSolve starts executing, the fun begins.
Assuming everything goes well, XYSolve will present you with
a "SYSTEM INTRODUCTION" screen. This screen is just a
reminder of some of the more important points in running the
program, such as how to move around within the menus, etc.
The comments on setting your particular system's SOUND, and
COLOR parameters are of primary importance. This is your
opportunity to configure your program for a particular
environment.
Page 5
Selecting the different parameters to change is done
with the <ARROW> keys and <ENTER>. Before XYSolve will let
you proceed to the system setup module, however, it first
checks to insure that your <ARROW> keys are active. If you
notice a "Please press your Number Lock key" request at the
bottom of your screen, that is what's happening. Now let's
take a little closer look at the SETUP procedures. We do
this by pressing <Y> for "Yes". The Setup window will open
with the selection bar highlighting the 'SOUND' option.
Press <UP> and <DOWN> a couple of times and notice how the
FUNCTION and COMMENT windows follow. When you stop at the
'SOUND' selection again, press <ENTER>. Pressing <ENTER>
will toggle the sound capability of your system on and off.
Let's set it 'ON' during this session. Finally, press <DOWN>
to select the 'COLOR' option. The COLOR option toggles
between the single 'NORMAL' screen color, and a repeating
sequence of 'ALTERNATE' colors. Just press <ENTER>
repeatedly until the desired color is active. When you
have completed setting the environment, you can get back to
the main stream by pressing <ESCape>. XYSolve will then
prepare a special file on your master diskette containing
your new settings, and will automatically use them as
defaults during future sessions. By now you have used almost
all of the important keys you will need to know as you
continue within XYSolve. Should it become necessary, you can
also review these key assignments by accessing any of the
menu 'HELP' screens.
Ready To Go On?
The next screen you will encounter as we proceed is the
'MAIN MENU'. This screen is the gateway to the rest of the
program. From here you can select Puzzles to be solved with
the START selection, obtain a status REPORT on your progress,
SAVE your current status for later re-activation, obtain HELP
and END a session. This screen also provides access to other
menus with selections of their own.
As you can see, the 'MAIN MENU' screen is primarily made
up of five windows:
The 'PLOT OPTIONS' window on the left.
The 'VALUES' window on the right.
The 'FUNCTION' and 'COMMENT' windows on the bottom.
The PLOT DISPLAY window in the center.
Page 6
You will become more familiar with this screen format as
we proceed.
As we have just arrived, the selection bar is
highlighting the 'MAIN MENU' option. By pressing <UP> or
<DOWN>; however, you may select other options. By pressing
<LEFT> or <RIGHT>, you can move into the FUNCTION window. Go
ahead and practice a bit. Notice how the selection bar wraps
around the end of it's range just as it did in the SETUP
window. When you are ready to proceed, select the 'MAIN
MENU' option once again.
START.
The first step in using XYSolve is to activate a puzzle
by selecting 'START'. Press <DOWN>, and you enter the
PUZZLE PREPARATION MENU where you may select either the
DISKETTE or the KEYBOARD as the source for your puzzle. For
now, we will load and activate one of the practice puzzles
provided on the XYSolve master diskette.
Puzzle File Directory.
Press <ENTER> or <RIGHT> and <ENTER> to obtain a
directory of all the Puzzle Files on your diskette. let's go
with an easy one first, one covering the TWO DIMENSIONAL
POINT.
Two Dimensional Point Math Module.
At the filename prompt, type "TWO-D" followed by
<SPACE>. After reading and analyzing the data from the file,
XYSolve will plot the point on the display, and we will be
ready to proceed with our solution attempt. From the MAIN
MENU, press <RIGHT> once then <ENTER>. These steps will place
us within the 'GENERAL MENU' level. In addition to the
change in the menu name listing, an entirely new set of
FUNCTION selections has been provided. All of the lower
level menu screens look exactly like this with the exception
of displaying their own set of appropriate functions. We are
now finally at the point where we can select a function to
solve. Use <ARROW> and <ENTER> to select '2D Point'. As we
enter the module, the function we are attempting to solve
blinks so that it can be identified among other forms that
may be present. Let's go over some of the other changes.
First, we finally have some values in the 'VALUES' window on
the right. In addition, the 'OPTIONS' window has completely
changed its contents as has the 'FUNCTION' window which now
displays the 'FORMULA' for our '2D Point'. Adjacent to the
appropriate formula, a variable is in a position to be
updated.
Page 7
Since the current plot display is used so much by
XYSolve, let's take just a second and go over some of its
points.
Main Plot Display.
First, notice the set of rulers for the "X" and "Y"
axis. These rulers define the two dimensions in which we
will be plotting while we are in this module. The normal
range of this particular set of rulers is +/- 10. You'll also
notice that "X=0" and "Y=0" points are defined by vertical
and horizontal axis lines. Using the rulers, you can see
that the currently displayed point is located at "X=5" and
"Y=5" or (5,5) for short.
Numeric Value Entry.
Our next step is pretty clear. As the comment window
states, we can select a new value for the variable "A"; or
simply by pressing <ENTER> accept the +0.0 that is currently
assigned. After we enter our selections for "A", "X", and
"B", XYSolve will plot the solution for us. As you enter the
following values, watch the screen carefully. Several things
will be happening in quick succession, and I will try to
point them out for you. First, go ahead and accept the
current +0.0 values for both "A" and "X" by pressing <ENTER>
twice. Next, change the value for "B" to -7.5 watching
carefully as you enter each part of the value... XYSolve
monitors each keypress you make, trying to figure out what
you want. When it thinks it knows for sure, it will move to
complete the entry for you. XYSolve knows all the rules of
the game, as well as the limits for each value. It knows,
for example, that SYSTEM LIMITS for variables are set to +/-
99, and that only one decimal place is allowed and then only
if the value is less than +10 and greater than -10. Don't be
intimidated by this, XYSolve only wants to help us keep our
plots under control. As you entered your keypresses, the
following sequence was taking place:
Your first key, the "-", told XYSolve that you didn't
want the currently assigned default value, so it cleared the
value and displayed your "-". Your second key, the "7", was
no help to XYSolve, so it just displayed it. Your third key,
the decimal point ("."), was more helpful. Now XYSolve can
figure out what you are doing and set itself up to assist
you. It knows to expect another number key (or <ESCape> if
you don't like your values) and will not allow other keys to
be accepted..except for one, <ENTER>. If during entry of a
numeric value, you press <ENTER>, XYSolve will assume you are
through and will complete the rest of your value, adding any
appropriate decimal point or zeroes.
Page 8
Your last key, the "5", was all that XYSolve needed, so
it provided the <ENTER>. Since you now have values for all
the required variables, XYSolve goes to work. The "B"
'VALUES' display gets updated and the plot moves to a point
along the "X=0" axis as expected.
First Waiting Position.
After completing each plot, XYSolve moves to a waiting
position. The 'COMMENT' window then displays key assignments
that are currently active.
PLOT OPTIONS menu.
Press either <UP>, <DOWN>, <LEFT>, or <RIGHT> once.
When you are at the waiting point, all arrow keys lead
to the 'CURSOR' plot option.
Press <ENTER> to select the cursor.
'CURSOR' Plot Option.
While in the 'CURSOR' module, you may use <LEFT>,
<RIGHT>, <UP>, or <DOWN> to align the cross-hairs with points
of interest on your plot. Go ahead and practice a bit. When
you are ready to EXIT, press <ESCape>.
'ZOOM' Plot Option.
Press <DOWN> once more to get to the 'ZOOM' Option.
It is possible within the numeric limits of XYSolve to
plot functions partially, or entirely outside the range of
the display. In attempting to identify these "hidden"
functions, you may toggle the display between the normal +/-
10 range and +/-100. Once identified, functions may be
solved in the usual manner. Let's take a quick look at ZOOM.
Press <ENTER> once to set the 'ZOOM' option to +/-100.
Notice that the plotted point seems to have moved toward
the center of the display, just as we would expect it to with
our scale change.
Press <ENTER> once more to reset the 'ZOOM' option to +/-10.
Page 9
'ENHANCEMENT' Plot Option.
Press <DOWN> and <ENTER>.
The inversion you are seeing is a technique used to
more readily identify plot features that might blend into a
background. The 'ENHANCE' option is a ON/OFF toggle like the
'ZOOM' option we used a minute ago.
Press <ENTER> again to turn it off.
'PRINTER' Plot Option.
Press <DOWN> and <ENTER>.
The 'PRINTER' selection allows you to save a copy of
your work on a printer. Both GRAPHIC and NON-GRAPHIC
printers are supported. We won't copy our current plot as it
can take several minutes to complete a printout.
Press <ESCape> to CANCEL the sequence.
'HELP' Plot Option.
Press <DOWN> one last time and <ENTER>.
The 'HELP' module identifies variables that are out of
tolerance causing a solution to fail. A failure may be due
to a single variable or possibly the inter-relationship of
several variables. The 'HELP' facility allows you to "lock-
in" correct values while attempting to "zero-in" on incorrect
ones. In establishing standard limits, XYSolve can augment
each correct value with a pre-defined tolerance. When 'HELP'
is active, XYSolve compares your input with the "standard"
limits. If an input exceeds the limit, the corresponding
variable is identified by a reverse color selection bar in
the values display. It is important to note however, that
the 'HELP' facility merely leads you to one "unique" solution
within the entire solution set for the function. Just as
there are numerous solutions for any algebraic equation, it
is possible, and entirely reasonable, to successfully
complete the solution for a function with any one variable,
or indeed all variables, exceeding the tolerance limits.
EXITING Plot Options.
There are a number of ways to EXIT Plot Options. We can
press <UP> four times; press <DOWN> once to wrap around the
menu range; or just press <ESCape>. Let's use the fast way.
Press <ESCape> to jump to the top of the 'PLOT OPTIONS' menu.
Press <ESCape> to EXIT from the 'PLOT OPTIONS' menu.
Page 10
Second WAITING Point.
Whenever we leave the 'PLOT OPTIONS' window, we
automatically enter the Second WAITING POINT. From here, we
may either EXIT the '2D Points' module by pressing <ESCape>,
or continue to solve new plots by pressing <SPACE>.
Since we turned the 'HELP' facility ON, let's enter some
values and see how it works.
Press <SPACE> to continue in the '2D Point' module.
Press <ENTER> three times to accept the values we setup
previously. Notice that all the variables are indicating
excessive values. As we would continue to refine our input
values, the out-of-tolerance indicators would extinguish.
Press <ESCape> to EXIT the '2D Point' module.
Press <ESCape> to EXIT the GENERAL MENU.
'REPORT' Menu Option.
As we have activated a puzzle, we are now able to obtain
a report on our progress.
Press <DOWN> twice and <ENTER>.
The REPORT module provides several pieces of information
that describe our performance as well as define the
complexity of each puzzle. Take a moment and review the
report criteria on the screen. While your at it, can you
explain our miserable score?
Press <SPACE>.
Press <DOWN>, <LEFT>, and <ENTER> to select the KEYBOARD
puzzle file preparation module.
Keyboard Puzzle Files.
The Keyboard Puzzle File Preparation module is extremely
handy when preparing and activating short Puzzle Files.
Let's prepare a quick Puzzle containing just a Circle.
Press <3> for a Tolerance value assignment of "0.3".
Press <3> again to select the 'Circle' module.
Enter a value of "1.0" for the "A" variable.
Enter a value of "3.0" for the "B" variable.
Enter a value of "5.0" for the "R" variable.
Press <ENTER> at the function prompt to activate the Puzzle.
A more in-depth explanation of Puzzle File Preparation
may be found in the Advanced Procedures section.
Page 11
'SAVE' Menu Option.
Press <DOWN> three times and <ENTER>.
The 'SAVE' module will copy our current status onto the
disk where it will remain until we wish to reactivate it. We
are now free to continue to solve for the copy which is still
in the computer. It is important to note however, that there
can be only ONE CURRENT STATUS file on the diskette at a
time. Thus the contents of any existing status file will be
overwritten with each new 'SAVE'.
As you may have already noticed, XYSolve will give you
the chance to reconsider your 'SAVE' request if it detects
the presence of a previous status file. Should you decide to
abort the attempt by pressing <ESCape>, XYSolve will
reactivate your present puzzle as if nothing happened. Just
for fun, let's load the puzzle from the "CURRENT.PZL" file.
Use your <ARROW> keys etc. to gain access to 'START', and
select the 'DISK FILE' option. Finally, enter "CURRENT" at
the filename prompt to load and activate the Puzzle.
'HELP' Menu Option.
Press <UP> twice and <ENTER> to select the 'MENU HELP' module.
As you have learned, XYSolve's menu system is multi-
leveled. You move from one level to another by way of the
<ARROW>, <ENTER>, and <ESCape> keys. All the menu 'HELP'
screens have similar diagrams to assist you in determining
how to get from place to place.
Press <SPACE> to return to the 'MAIN MENU'.
This just about completes the "Grand Tour". There's
still lots to see and do within XYSolve, but for now, you
have a good idea of how to:
Move around within the menus and modules.
Work the various displays.
EXIT back out.
One last thing, to 'END' using XYSolve, you merely
have to press <UP> and <ENTER>.
That's quite a bit for one session, Let's take a break!

XYSolve Functional Modules
==========================
XYSolve functional modules are designed to provide a
rich educational environment. Each function has been
provided with as much interactive flexibility as is suitable
for its form. The following individual explanations cover
some of the more important aspects of each module such as the
type of input expected and possible error messages. In
addition, several of the advanced modules are covered in more
detail in other parts of this manual.
================================================================
Functional Module: 2D Point.
Formula: Y=AX+B
Description: Plots a point on a two dimensional plane.
Discussion: The Two Dimensional Point module accepts one
positional and two parameter values which are used
to define a position on a two dimensional plane.
** Warning! ** Messages: None.
================================================================

XYSolve Advanced Procedures
===========================
XYSolve implements advanced procedures such as Puzzle
File Preparation, and Parametric and Composite routines.
Preparing Puzzle Files:
The format required by the Puzzle File system is
straightforward in that there is only three types of
information "required" to complete a file; a TOLERANCE value,
Function NAME, and NUMERIC VALUES for any associated
variables. In addition, an optional non-displayed COMMENT
may be added to each line in the file to explain it's usage.
In establishing "standard" limits for variables, XYSolve
can augment the normal "exact value" solution criteria by
adding the pre-defined tolerance value. A single tolerance
is active for each solution set, and is saved with the puzzle
on diskette. As you become more familiar with a solution
set, you may choose to tighten-up the tolerance value, or
even eliminate it altogether.
TOLERANCE VALUE Recommendations:
"0.0"-"0.3" Advanced level users or simple functions.
"0.4"-"0.6" Intermediate level users and functions.
"0.7"-"0.9" Novice level users or advanced functions.
The syntax requirements for the Tolerance value and all
other numerics within a puzzle is the same. Each value must
occupy it's own line, contain a prefix of "#", and be
followed by at least one space!
NUMERIC Examples:
#0.1 comment recommended.
#2.3
#45
#-0.6
#-7.8
#-90
Page 18
Sequences of FUNCTIONS with their associated variables
follow the tolerance value in the Puzzle file. There is no
theoretical limit to the number of functions (pieces) that
can make up an individual puzzle; however, there is a
practical limit to the complexity of a display. Too many
pieces, poorly placed, can make a puzzle overly difficult to
solve. A full listing of available functions and associated
variables can be found in the "Functional Modules" section of
this manual.
Puzzle function sequences may be developed by
documenting your keypresses as you go through the steps to
manually accomplish your desired goal. Once the steps have
been listed, you merely prepare a TEXT file containing your
values. Don't be overly concerned with this procedure. I'm
sure you will find it significantly easier than writing a
letter with a common word processor. If an error is found
when you try out the puzzle, merely re-edit your TEXT file
and try again..
The required syntax for puzzle functions is even simpler
then that required for numerics. Each VALID function name
must occupy it's own line, and like the numeric, be followed
by at least one space!
FUNCTION Examples:
LINE comment recommended.
Parabola
circle
SiNe (Upper/Lower case okay.)
COMMENTS are highly recommended! An optional comment
can be added to each line in your file. As your work becomes
more sophisticated (lengthy), remembering exactly where you
are in a sequence at any particular moment may become more
and more challenging. The liberal use of comments can do
much to alleviate this problem. Please note however, that
comments, if used, may extend only to the end of the current
line.
Page 19
PUZZLE Filenames:
XYSolve is designed to assist you in managing large
numbers of Puzzle files. It does this through a unique file
extension technique. All Puzzle files are assigned
extensions of ".PZL". If you are preparing your Puzzle files
with a general purpose text editor, you will have to
explicitly assign this extension. If however, you are using
the system editor XY-Edit, it will assign the extension for
you automatically.
** WARNING! **
Puzzle files that are mis-labeled will not be able to be
selected for use by XYSolve.
You may obtain further examples of function and numeric
variable usage by printing out the practice Puzzle files
that have been provided on your XYSolve master diskette.
In addition, the required syntax is diagrammed in the
Appendices.
Page 20
Parametric/Composite Procedures.
The 'PARAMETRIC' and 'COMPOSITE' functional areas are
advanced modules designed to display the effects of parameter
changes on "systems" of related equations. Each group solves
two individual equations simultaneously. In the 'PARAMETRIC'
modules, the equations are related through a common parameter
such as "T". Changes due to this shared parameter will be
reflected in the contribution each formula makes to the form
of the combined display. In the 'COMPOSITE' module, the
individual equations are related by their solutions for "Y"
at identical values of "X". For example, if your solution at
a particular "X" results in a value of "5" for "Y" when using
equation #1, and "-5" using equation #2, the resulting
combination plot could have a value of "0". The plot for
equation #1 would place a point at location (X,5), and
equation #2 at (X,-5). The combined display would have its
point placed at (X,0). A second major difference between
Composites and Parametrics is that the Parametrics are solved
using perpendicular axis, i.e. "Y=f(T)" for one equation and
"X=g(T)" for the other. Composite equations however, are
usually solved along a common axis, say "(gof)(X)=g(f(X))".
Composite equations are not restricted to any arbitrary
type. The equation for a line might be combined with one for
a curve, or two curves might be combined, etc. XYSolve
provides examples of each of these standard types.
Interesting examples of both Parametrics and Composites
are provided in the Appendices.
Page 21
Using the PRINTER:
XYSolve has built-in support for both GRAPHIC and NON-
GRAPHIC printers. All you have to do to print out a plot is:
1. Insure that your desired plot is on the screen.
2. Enter the PLOT OPTIONS MENU and proceed to the
PRINTER selection.
3. <ENTER> the PRINTER module.
4. Select an EPSON compatible printing mode. Your
printer's manual will help in selecting the best mode
for your particular system..
5. Follow the directions and insure your printer is ON
LINE and ready with paper etc., then press <SPACE>.
That's all there is to it!

specified by the user.
DOS: Your Disk Operating System is a collection of procedures which
enables your computer to execute programs like XYSolve.
Page I-2
E
ERROR message: A message displayed on the screen which informs
the user of an anomalous condition. Consult the ERROR message
listing in the Appendices for message specific information.
F
File: A collection of related information stored on your disk. A
file can contain either programs or data. Puzzle files, and
the INSTALL program are examples of disk files used by
XYSolve.
Foci: A point whose position can define the form of an ellipse,
hyperbola, or parabola. It appears as the source or
destination of rays.
Function: A correspondence that assigns to each element x of X a
unique element y of Y. NOTE: The term "Function" is used to
describe a particular module within the XYSolve system,
regardless of whether it meets this rigid definition or not.
That is to say, the circle is a functional module in XYSolve.
Functional module: See Function.
Function window: The area at the bottom of a common XYSolve
display that lists menu selections, active keys, or input
requirements.
