QuantumJG:
Find the Fourier coefficients of

now I know that since this is an even function that implies bn=0

But what about an?

Now I know:



But for some reason even using the standard integrals I keep getting an to also be 0.

Can somebody help?

EDIT: WHOOPS!

So



Thanks!

Ahmad:
I think you missed an absolute value around sine in the integral.

/0:
Hmm I'm just wondering, why did you put instead of

We haven't covered Fourier Series yet, but reading ahead in my book that's the formula they give.

Given a fixed value of I tried the latter formula and got:



Fourier analysis is cool

Cthulhu:
My textbook uses

too.

Definately

The only problem is that we do this last, since we do electromagnetism first then optics (I may actually come to love optics). Having said that electromagnetism looks pretty cool too.

With the formula I gave, both forms are equivalent its just my lecture notes use what I put up.

In our lecture notes:



So I thought that if:
