I have a quantum physics 2nd year undergraduate exam in a few weeks, I'm a complete beginner to fourier series, can anyone help explain how to answer this question please? Thanks, rob.

Thanks mate, yep i essentially understand, just 1 question though:
How did you get from the second line to the third line in the following:
\begin{equation*}
\begin{split}
\int_{-T/2}^{T/2} f(t) \sin{n \omega t}\ dt &= \int_{-T/2}^{T/2} \left[ \sum_{n=1}^\infty b_n \sin{n \omega t}...
The Fourier Series!!
Hi guys, i'm having a bit a trouble helping my daughter with this question on the fourier series approximation:
The fourier series for a real, odd function, f(t) can be written as:
f(t) = [SUM to infinity, n=1, of]: b[subscipt n] sin(nwt)
where f(t=T)=f(t) and...
