The exact values of the trigonometric functions of , , , , and are well known.

In this problem, means the inverse tangent function, the angle whose tangent is ,
which happens to be ,
but the cotangent of any angle is the reciprocal of the tangent (if they both exist), so we know that
,
just as we also knew that
Putting it all together,
