1. ## integration

Dear all; I would like to ask q question about fourier transform (or integration).

I would like the proof why equation 1 and 2 make the third equation - i.e. the fourier of equation 2 is equal to equation 3.

Thanks a lot

Are you sure you have equation 2 down right? Consider what happens when $x$ goes to $-\infty$(assuming $\alpha>0$, or if $\alpha<0$ as $x$ goes to $+\infty$).

3. ok Sorry my mistake the limits of integration are from 1 to n . and alpha is a positive number greater than zero thanks
