comment Deriving Taylor series for function from geometric series
@J.M. I don't actually know how to expand it, it's just given to me and I memorized it.

comment Deriving Taylor series for function from geometric series
@J.M. Sorry but i don't get it. The last few questions I have been doing is more along the lines of $\frac{1}{3-2z}$ with center at 1. which rearranges to $$\frac{1}{1-2(z-1)}$$ which looks very similar to the geometric series $$\frac{1}{1-z}$$. I substitute 2(z-1) into z from geometric series and get my answer.

@J.M. Thanks, but I still don't seem to get how this can be fitted into the Geometric Series, can you elaborate a little please?

comment Finding Fourier series with function not centered at the origin
@LeonidKovalev why is$ \int_{-\pi}^\pi f(t)\sin nt\,dt=2\int_{0}^{\pi/2} f(t)\sin nt\,dt$ ?
