# Thread: Is there any way to computationally calculate a fourier series?

1. ## Is there any way to computationally calculate a fourier series?

Ordinarily, I check my answers by plugging the problem into Wolfram Alpha. But I'm not aware of a way to do this when it comes to finding a Fourier Series of an equation or system of equations. This is especially true if it's a periodic set, as I have no idea how to supply the condition that $\displaystyle f(x + p) = f(x)$.

Is there any way to calculate this, either via Mathematica, MATLAB, Wolfram Alpha, or something else?

Can you be more specific?

Every text gives the method of finding coefficients and the series representation, exactly what is it you require in addition to those?

As I said in my original post, I am looking to check my answers. Ordinarily, I plug the equations into Wolfram Alpha so I can compare the result I obtained with theirs. However, I am not aware of a way to do that with this class of equations.
