Your code contains syntax errors. One of the problems seems to be:

sin^2(j*2*pi/N)


Did you mean (sin(j*2*pi/N))^2?

Your code contains syntax errors. One of the problems seems to be:

sin^2(j*2*pi/N)


Did you mean (sin(j*2*pi/N))^2sin(j*2*pi/N)^2?

Seems like this is the only error.

Your code contains syntax errors. One of the problems seems to be:

sin^2(j*2*pi/N)


This is being interpreted as sin^(2(j*2*pi/N)), which is problably not what you meant. Did you mean sin(j*2*pi/N)^2?

Seems like this is the only error.
