    FA 2 | Computing Fourier series

    I’d like to talk to you now about computing Fourier series. Now, just because it’s a computation doesn’t mean it’s routine or boring. In fact the ideas behind computing Fourier series are the start for much deeper ideas in math, and I think they are pretty interesting in their own right and I hope by the end of the video you’ll agree with me. When we get to the key idea of this computation we’re going to need the values of some integrals. So let’s discuss those (in order to prepare for that.) Now these integrals will involve some integers so let’s let ‘k’ and ‘l’ be the positive integers.…
