I have trouble solving the following sum:
I've tried the following:
The first term is:
The sum is than:
but this is incorrect.
Any help to compute this sum would be appriciate it. Thank you

... it has been demonstrated that the 'mirror imaging' of the function...
(1)
... has the following Fourier series expansion...
(2)
Setting in (2) You obtain...
(3)
... so that is...
(4)
Kind regards
So to compute the following sum:
... has the following Fourier series expansion...
(2)
Setting in (2) You obtain...
(3)
for this fourier expansion (using Parseval):
..and I get the following:
But this is incorrect answer. What am I doing wrong here?
By the way, thank you for your response.
Kind regards
Since the given function is even, continuous and its periodic with period , I get the following when I compute ...
in this case ...
Am I using a correct formula to compute ?

In our course book says that the Parseval's identity is:The Parseval's identity is...
(1)
(4)
But when I apply (4) to the the same problem above I get a different result. Why is that? But your result is the correct result according to the answer in the problem book.
I used and the limits for the integral . I also tried with , but still get different result.

I would like to ask you kindly to write out all the terms without simplifications in other words:
Thank you
Kind regards
