# I need help on how to do this integral

∫exp(-x^2/k) *cos(2*pi*s*x) dx from -infinity to infinity

So this integral is an error function unless I take the definite integral from -infinity to infinity.

Will this give me a pretty answer in I do this with the limits specified?

Yes, it will; try it and see.
