hey guys need some basic help in Fourier series..
these are a couple of problems i got stuck at...

1. f(x) = 50 -8<x<-2
= 0 -2<= x<= 4


2. f(x) =Sin x 0<x<= pi
= 0 pi <= x<= 2pi

3. f(x) = 0 0<x<1
= 1 1<= x<= 2

please help guys/..

What have you tried so far?
Do you recognize that 1. and 3. are essentially the Heaviside Step-function?
 

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
