## Further Sums Found Through Fourier Series

In an earlier insight, I looked at the Fourier series for some simple polynomials and what we could deduce from those series. There is a lot more to be found, however. Evaluating the Fourier series at π/2 First series In the last insight, I showed that if f(x) = x for -π<x<πand f(-π)=f(π)=0, the general […]
