There are a few formulas for calculator to compute the angles and sides, knowing the measures of some.

1. Pythagor Theorem: c^2 = b^2 + a^2

2. tan A = a/b; cos A = b/c; sin A = a/c

3. b = c*cos A; a = b*tan A

To solve a right triangle, we don't need a graphing calculator. Graphing calculators are mostly used for graphing functions.
