## Trigonometry: Inverses of Trigonometric Functions

Trigonometry: Inverses of Trigonometric Functions (1) Evaluate exactly tan(Arccos 2/3 ). (2) Evaluate exactly cos(Arcsin 1 + Arccos 1/2 ). (3) Determine arcsin (1/v 2) . Careful: that is arcsin and not Arcsin, so there are going to be infinitely many answers. You need to give all of them. (4) Evaluate exactly sin( 1/2Arcsin4/5 ). […]
