I am attempting to solve the below problem: I was able to calculate the N point DFT for a cosine which is similar to this (note, this is the DFT for $\cos(2\pi n k/N)$.

1. −1 cos(x).

Radical Expression For cos(2pi/7) We sometimes wish to express the values of trigonometric functions for some rational multiple of pi as a radical expression. For example, we might wish to express cos(2pi/7) as a radical function of rational numbers. However, solutions by radicals are sometimes less helpful than one might think.

The expression cos 2pi/15 cos 4pi/15 cos 8pi/15 cos 16pi/15 is 2010-06-25 · I feel that there should be a slightly more elementary way to show this, although it should be technically the same. If we let j_{n} = cos(2\pi/n) For real number x, the notations sin x, cos x, etc. refer to the value of the trigonometric functions evaluated at an angle of x rad.
