====================
  GRAPH3D PRO V3.0
====================
   by TICalc Arts


==================================================================================
INTRODUCTION:
==================================================================================
This is the first and only 3D graphing program for TI calculators that has more
than one mode. This program will allow you to plot 3D graphs using Cartesian,
Polar, Cylindrical, and Spherical coordinates.

This version (V3.0) is available for the TI-84+CSE/CE/Evo only.

Prior versions of this program are available for the following calculators:
TI-73/82/83/83+/84+/85/86


==================================================================================
PLOTTING:
==================================================================================
When you run G3DPRO, you will be at the MODE select screen. Select a mode by using
the [F1]-[F4] keys. If a previous plot is available, the current equation will be
shown and you may press [F5] to plot it.

The 4 modes available are:
F1: Cartesian: Z(X,Y)
F2: Polar (or Conical): Z(R,theta)
F3: Cylindrical: R(Z,theta)
F4: Spherical: R(theta,phi)

After selecting a mode, you can edit the current equation and window. Press the
arrow keys to select which window parameter you would like to change and press
[ENTER]. From there, you can enter the value you want. Once you have the window
settings you want, you can press [F5] to plot the current equation.

Note: If you change modes, the default equation and window settings will be reset.

Here are some example equations you can try using the default window settings:

Z(X,Y)=5cos(90/pi*sqrt(X^2+Y^2))	Note: Trig mode is auto-set to DEG.
Z(R,theta)=2sqrt(R)
Z(R,theta)=theta/60
Z(R,theta)=3cos(120R/pi)
R(Z,theta)=Z^2/6+2
R(Z,theta)=theta/60
R(theta,P)=5
R(theta,P)=P/60


==================================================================================
VIEWING:
==================================================================================
Note that X and Y are horizontal and vertical, respectively. Z is in and out of
the screen.

Arrows	= Rotate graph 15 degrees
8/2,4/6 = Rotate graph 90 degrees
[MODE]	= Toggle Wire/Dots
[ALPHA]	= Toggle Depth Perspective On/Off
[XT0n]  = Bounding box On/Off
[STAT]  = Axes On/Off
[VARS]  = Change color scheme
[+]/[-] = Zoom In/Out
[ENTER] = Reset Zoom
[TRACE]	= Trace mode
[CLEAR]	= Quit



==================================================================================
TRACING:
==================================================================================
When you enter TRACE mode, the equation will be displayed at the top of the screen
along with the values for each point selected. Press the arrow keys to select
different points in the plot. Press [ENTER] or [CLEAR] to exit trace mode.
