prgmCHANGE:	Performs transformations upon shapes you define with any number of sides
		Requires: prgmCHANGE, prgmMATH, prgmZMID

prgmMATH:	Gives line equations for two points (gives midpoint and distance too,)
		converts linear equations from y=mx+b form to c=ax+by form, or c=ax+by
		form to y=mx+b or x=my+b form, calculates intersects of linear lines
		after you enter equations, and can draw shapes
		Requires: prgmMATH, prgmZMID

prgmCOSINE:	Calculates angles and sides of a triangle after you enter some basic data.
		Very user friendly: quick, easy, accurate.  Choose radian or degree, 3 sides
		or 2 sides & 1 angle, draw diagram of sides for easy comprehension.
		Requires: prgmCOSINE, prgmZMID

prgmZMID:	Needed to run other programs in file.

Total Mem Used by Programs: 2875 bytes (TI-83 RAM)

To install:	Unzip mathpack.zip into a directory of your choice.  Use a link program to
		transfer mathgrph.83g and cosine.83p onto your TI-83.  Run any of the programs
		to use.  Delete real variables after use, as they may mess up other programs in
		the pack.
