INTRODUCTION

Graph is a 3D grapher for your TI-83+ or TI-83+ Silver Edition.
______________________________________________________________________

INSTALLING

Send the "graph3.8xk" file to your calculator using a graph link. You
must have a link; applications cannot be typed in by hand.

To install, press APPS and then select Graph from the list. A message
box will popup, instructing you on how to proceed. (If you have other
graphing apps installed, for example, Inequality or Transformation
graphing, you will be asked to uninstall them.)
______________________________________________________________________

USAGE

To enter 3D mode, press Y= twice. You will remain in 3D mode until you
push a key that exits graph mode (examples: 2nd QUIT, program editor,
memory check, etc). Graphing is very similar to the normal function
graphing on the 83+, with the following differences:
- There are only two graph styles: wireframe (thin line) and hidden
  surface (filled triangle)
- The "X,T,theta,n" key inserts X as usual, but STAT inserts Y.
- Only 3 zooming options are available. Also, the cursor for zoom in
  and zoom out point selection is the same as the trace cursor to
  increase visibility.
- The Format menu has less options. Also, selecting PolarGC in 3D mode
  is the equivalent of a cylindrical coordinate system.
- Stat Plot, TblSet, Calc, and Table are not available in 3D mode.

There are also the following additional features:
- When viewing a graph (no cursor), push GRAPH again to instantly
  toggle the graph type between wireframe and hidden surface.
- Whenever viewing a graph, press ALPHA X, ALPHA Y, or ALPHA Z to view
  the graph from that axis.

UNINSTALLING

To uninstall, simply run the application again (from the APPS menu).
It should display a message indicating that it has been installed.

IMPORTANT: Do not let other applications uninstall Graph, nor should
you delete Graph if it is installed.

BUGS

If you find any bugs not already listed below, please send email to
graph3@kirkmeyer.org and be as descriptive as possible. If possible,
include the equation you were trying to graph, the window settings,
the format settings, and any applicable information.

Known issues that I plan to solve:
- Cannot use Calc to enter abstract coordinates in trace mode.

Known "issues" that I do not plan to solve:
- 2nd-Left and 2nd-Right do nothing when viewing/tracing the graph.
