I am having trouble with fourier series, can anyone point me in the right direction with the question. The graph has been attached.

f(t+3) = f(t)

The fourier representation of f(t) is given by

f(t) = $\frac{ao}{2}$ + Ʃ ancos$\frac{2npit}{3}$ + bnsin$\frac{2npit}{3}$

Determine the coefficient b2

Thank you.

The coefficients are given by an integral, which you have probably gotten in your class. If you show us your work and where you're getting stumped, we can help you better. But we usually won't do the problem for you...
