    3. The attempt at a solution

    I don't understand where that 2 comes from in the denominator in cos nπ/2

    Instead of trying to follow somebody else's presentation, just sit down and do the integrations yourself. That way, you will answer your own question, and will *understand it much better than if somebody else showed you how to do it*. I really believe that.

    of course i always do my own derivation. my own derivation is -cosnπ/524nπ - 1/524nπ

    There, I'm still as clueless I was before.

    So, you claim that 524/1048 = 1? That is the only way you could end up with what you said.
