Help(Using a fourier series to find the sum of second series

[LCKurtz]

Yes, that is the theorem you want to use. But it won't be of any use to you until you figure out how to extend the definition of f(x) to get an odd continuous periodic function.

You do have an instructor you can talk to, don't you? You don't need to apologize for being a "newbie" or not understanding a subject. But I do think, from our discussions, that you really do need to go over this problem with your instructor. There are several pretty basic things I think you don't understand.

okay so that theorem in my previous post its userable here either ??

my instruction gave me the extra day to solve this problem under the condition that could come with a solution. So I can't ask him.
