1. The problem statement, all variables and given/known data
Find the fourier series coefficients X_k of the periodic signal: x(t) = 5cos(6w_0t+pi/2) (digital or discrete spectrum) 2. Relevant equations 3. The attempt at a solution I am really confused with all of this and don't even know how to start.

What do you mean by "digital or discrete spectrum" ? The '(t)' in x(t) designates a continuous time dependent signal.
Anyway, are you familiar with the 3 coefficients (a0, an, & bn), the way the fourier series will be represented after you find them, how to calculate each one, and any shortcuts (like an odd or even function) that may hasten the process?
