## Homework Statement

If I'm given a potential say A(x/a-m) m an integer, (this is the sawtooth wave)

What kind of trial function should I use to approximate this?

## Homework Equations

## The Attempt at a Solution

I do recall this function arising in Fourier series. Should I actually solve for the Fourier coefficients to get a trig function? Maybe I'm making this more complicated, is there a simpler way to do this?
