Homework Statement



V = span(S) where S = {(1, i, 0), ((1-i), 2, 4i)}, and x = ((3+i), 4i, -4)

Obtain the orthogonal basis, then normalize for the orthonormal basis, and then compute the Fourier coefficients.

Homework Equations



v2 = w2 - (<w2,v1>)(v1)/(||v1||²)

The Attempt at a Solution



So using this above equation, I get ||v1||² to equal zero because 1 + i² = 1 - 1 = 0, thus I'm dividing by zero, so where do I go from here, or am I miscalculating somewhere?

How do you compute the square-norm of a complex number?
 
Ok this is what you did wrong:

||v1||² = v1* . v1 = (1, i, 0)*. (1, i, 0) = 1+(-i)(i)=1+1=2
 
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...
