    Fourier transform

    How do i go about finding the fourier transform of 1/(1+t^2) ?

    I guess I'm suppose to integrate it from 0 to infinity, but it seems pretty hard: e^-j2pi*ft/(1+t^2) dt

    Shouldn't the integral go from ∞ to + ∞? In which case, you should be able to evaluate it by contour integration.
