Linear Solver app functions

	The Linear Solver app has 3 functions that offer the user
	flexibility in solving 2x2 or 3x3 linear systems of equations.
Solve2x2	Solves a 2x2 linear system of equations.
	Solve2x2(a, b, c, d, e, f)
	Solves the linear system represented by:
	ax+by=c
	dx+ey=f
Solve3x3	Solves a 3x3 linear system of equations.
	Solve3x3(a, b, c, d, e, f, g, h, i, j, k, l)
	Solves the linear system represented by:
	ax+by+cz=d
	ex+fy+gz=h
	ix+jy+kz=l
LinSolve	Solve linear system. Solves the 2x2 or 3x3 linear system
	represented by matrix.
	LinSolve(matrix)
	Example:
	LinSolve([[A, B, C], [D, E,F]]) solves the linear system:
	ax+by=c
	dx+ey=f

Triangle Solver app functions

The Triangle Solver app has a group of functions which allow you to solve a complete triangle from the input of three consecutive parts of the triangle (one of which must be a side length). The names of these commands use A to signify an angle and S to signify a side length. To use these commands, enter three inputs in the specified order given by the command name. These commands all return a list of the three unknown values (lengths of sides and/or measures of angles).
