# Gamma function

## Homework Statement

Prove $$\Gamma(1/2)$$ = $$\sqrt{\pi}$$

hence proove $$\Gamma(3/2)$$ = ($$\sqrt{\pi}$$)/2

solution

i have proved the first part by using sustitution and changing to polar co ords.
To prove the the second part i guess i dont have to work it all out again. i know that $$\Gamma(x+1)$$ = x $$\Gamma(x)$$ but i cant this to help me...

oh my god im an idiot, staring me in the face hahaha
