How do you solve right triangles using a graphing calculator?
Given a right triangle ABC, with c as hypotenuse, a and b as sides.
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 = ccos A; a = btan A
To solve a right triangle, we don't need a graphing calculator. Graphing calculators are mostly used for graphing functions.
