Did anyone else get an alternating cosine series for #21? The hint has a series that is always positive.

Same problem here.

Never mind. The terms in the series do alternate, but cos(n pi) also
alternates for increasing, integral values of n. This happens when f
is evaluated at t=pi (as opposed to at t=0).
