Homework Statement
Find Fourier series of f(x) = Acos([itex]\pi[/itex]x/L)
I know how to do this, I just don't know the value of L. If it's equal to [itex]\lambda[/itex]/2, then I know the solution. But the question does not specify the value of L. L is just the length of the entire wave that I'm working with, right? If it's [itex]\lambda[/itex]/2, then that's only half the wave, but the answer to the question works out to be what the solution manual says. How was I supposed to know that L = [itex]\lambda[/itex]/2? The only information given is what I wrote down.
Thanks
