Phase spectrum of a fourier series.

Hi again.

I have this piece of work which involves plotting a phase spectrum graph for the series in the attached image.

I am a bit stuck. I know that I will get the information from the cos terms outside of the brackets, but as w equals (2pi / T), won't each of those terms be a multiple of 2 pi, and therefore be the same phase?

Cheers.

Yes the phase at each discrete frequency will be the same - so you will plot the discrete magnitude and phase vs frequency values accordingly.
