Let θ be an angle with a terminal point of P shown in the picture below, and let Q, R and S be the following other terminal points:

Order the points P, Q, R, S so that so that the first point is the terminal point of arccos(sin(θ)), the second point is the terminal point of arctan(tan(θ)), the third point is the terminal point of arcsin(sin(θ)), and the fourth point is the terminal point of arccos(cos (θ)).

The correct ordering is S, P, Q, R.
