# Fourier transform of a Gaussian

Kolahal Bhattacharya

## Homework Statement

I need to have the Fourier transform of a Gaussian

## The Attempt at a Solution

∫(exp[-ax^2])(exp[-ikπx]) dx

I tried by braking the last exponential into sine and cosine terms.The sine term is odd and it cancels.Then,I cannot evaluate the remaining part.Please help.
