Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to integrate an expression I derived from multiplying the Fourier transform of two Lorentzians together. The expression is

[tex]\int^{\infty}_{-\infty}{dt.e^{-|t + \tau +a| - |t-a|}[/tex]

How do you go about solving this? I tried splitting it up but you have two different values of t where a sign change occurs...

Any help would be appreciated :)
