Hello,

I need help with question #2 c) from the following link (already LateX-formatted so I save some time...):

I do understand that the a0 for both expressions must be the same, but what about an and bn? I don't understand how you find them, given that we'll have an*cos(nx)/bn*sin(nx) in the first case while we will have an*cos(3nx)/bn*sin(3nx) in the second case.
