Hi,

I am being asked to express x(t) = r(1-cos(t-phi)) as a trigonometric Fourier series. I understand that I have to use trigonometric identities to simplify this before I integrate this using my limits (2pi and zero) then sub in my limits and take one from the other to get my ao value.

The problem is, I don't quite understand how I apply the trigonometric identities to this. Any help would be greatly appreciated.

Cheers!
