Inverse Trigonometric Functions

Run trig functions backwards: from a ratio to an angle, using restricted domains so the answer is unique.

About 16 minutes

You'll learn to

→Know the ranges of arcsin, arccos and arctan
→Evaluate inverse trig functions at key values
→Simplify compositions like cos(arcsin x)
