Solving Right Triangles Using Trigonometry

In this video we use basic right triangle trig (sine, cosine, and tangent or SOHCAHTOA) to solve right triangles. First we talk through what it all means and then we solve two right triangles completely. Along the way we use the trig functions, the inverse trig functions, and Pythagorean theorem. We also make use of the TI-Nspire CX (or CX II, or CX II CAS) to find approximations and simplify our calculations. We also have to change from Radian to Degree mode before we use the calculator.

You didn't have a function where you didn't have a degree. Thats how most of the questions start off as. Not this easy.
