Numerical Analysis II Project 0

For the first project we were to put a picture of a sine function on the website. I accidentally deleted the original version so in addition to a sine function, I will put up a function that has a sine term in it. Here is a picture of a sine function:
y=sin(2x)

Here are pictures that have a sine term in them:
y=sin(2x)

They are the actual and approximate laplacian for the function \[y=e^{\cos (2\pi x) \cos (2\pi y)}. \] The laplacian has sine terms in it. The approximation was done using a Fourier spectral method. The program used to calculate the approximation is here. The program was written in an unsucessful attempt to create a spectral solution to the Brusselator. The function is the only working outcome from the attempt to find a spectral solution.
