$$\int\limits_{0}^{\infty} t e ^{iwt}dt$$

anonymous · Answer

I can use mathematica. But I dont quite get how to get from this integral to the answer. Any help is appreciated

anonymous · Answer

It seems to me that the integral doesn't exist - if you integrate by parts you end up with a term that is infinite at the upper limit (at least that is what I found, I could be wrong).

Hint: your results from mathematica should tell you whether there is a problem with your integral
