I am a student studying Computer System Engineering. I have only arrived on the software scene very recently, and stumbling upon this site is probably the best thing that could have happened to me. I have learnt a good deal from all the people on here, and I hope one day I'll know enough to begin helping others as others have helped me.

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.

comment Deriving Taylor series for function from geometric series
@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$ ?

comment Finding Fourier series with function not centered at the origin
@RaymondManzoni Thanks for your help, I have now worked out half the question for when it's Even, but what would f(x) be like when it is Odd?

comment Evaluating Integral with Residue Theorem
Thanks, so I just want to check, is it possible for the integral to be 0 even if there are poles inside the path of integration?
