1. The problem statement, all variables and given/known data
It seemed much easier to screencap than to write out. 2. Relevant equations It helps to know that the number of states with speed between u and u+du is 2pi*u du 3. The attempt at a solution I've tried quite a few things but every time I get to trying to normalise I either get stuck integrating by parts over and over, or using http://en.wikipedia.org/wiki/Gaussian_integral<that, which doesn't arrive at the answer wanted. If someone could give me a push in the right direction it would be much appreciated.

You need some substitution to make the integral doable.

Ok so I have the integral of v*exp([tex]\alpha[/tex]v^{2}) dv between 0 and infinity to normalise. I don't know how a substitution would help because you would still have two functions multiplied by one another.
Edit: I think I'm being stupid. I've substituted for alpha*v^2. Hopefully it will work.
