Exponential fourier series expansion

AI Thread Summary
The discussion revolves around a student's confusion regarding their solution to an exponential Fourier series expansion problem, which differs from their lecturer's answer. The student, Mitch, initially believed their approach was incorrect due to not simplifying the equation based on the odd function property of x(t). Upon further examination, it turns out that both Mitch's and the lecturer's answers are indeed the same, leading to a moment of relief and humor about the misunderstanding. The exchange highlights the importance of verifying calculations and understanding function properties in Fourier analysis. Overall, the conversation emphasizes collaborative learning and the resolution of academic confusion.

Hey, thanks for taking the time to look ay my post (:

I have attached a file which shows the question I am stuck on, and my attempt at working it out.

My problem is the answer I get, is different to what my Lecturer gets (shown in the attachment). He worked it out a different way to me, he did not take into account that you can simply the equation Cn as x(t) is an odd function (This is all shown in the attachment).

This is where I would like some help, could some kind chappy please have a look at my work and maybe point me in the right direction if I have gone astray, or even tell my why the answer I have got occurs if it is correct?

Thank you very much, MitchThe question and attempt at solution:

Your and his answers are the same!
-j = 1/j
 
Now I feel stupid haha!

Thanks though (:
