    Any ideas how to solve this?

    \int{e^{- x^2}e^{i3x}}dx

    I would use a calculator. ;)

    But honestly, no. no I dont. It looks oddly familiar though.

    How about integration by parts?

    The Wolfram online integrator gives an answer ....

    \frac{\sqrt{\pi}erf(x-\frac{3i}{2})}{2e^{\frac{9}{4}}}

    Looks a tough one to derive from first principles.
