Hard Trigonometry Problem
Hard Trigonometry Problem

The SAT contains a very small number of trigonometry questions. Today I would like to provide an example of a particularly hard trigonometry problem that could show up.

Level 5 – Trigonometry

It is given that cos x = k, where π < x < 3π/2 and x is the radian measure of an angle. If cos z = –k, which of the following could not be the value of  z ?

(A) x – π
(B) π – x
(C) 2π – x
(D) 3π – x

Please feel free to post your solutions or attempted solutions in the comments below and we can discuss the best way to solve the problem. I will post several solutions to this problem tomorrow.
