I need help on how to do this integral

  1. Nov 15, 2013 #1
    ∫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?
