the question is on fourier transforms and i am stuck on how to approch the integral(adsbygoogle = window.adsbygoogle || []).push({});

INT[ (1/(2*pi))*e^(ik(x-y)-(1+ik)ct) dk

i know that the integral INT [(1/(2*pi))*e^(ik(x-y-ct)) dk] yields the delta function

= DELTA(x-y-ct) but the terms in the exponential from the integral in question have stumped me

any ideas would be great, cheers
