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

I'm having problems integrating the following function:

[tex]\int^\infty_{-\infty}Ae^{-\lambda(x - a)^2}[/tex]

Where A, [itex]\lambda[/itex], and a are positive, real constants. If anyone could point me in the right direction I'd really appreciate it.

The integral is supposed to be equal to 1 and using that fact I'm supposed to solve for A. This is from Griffiths' Quantum Mechanics Chapter 1.
