### Gamma function question

Hi, I'm confused about how to find the value of this specific problem. The answer is supposed to be (1/2) * sqrt(pi), but how?

If gamma(1/2) is = sqrt(pi), what is gamma(3/2)?

Do you remember the identity Gamma(n+1)=n*Gamma(n)?

The limit operator is just an excuse for doing something you know you can't.
