Prove that
Г(n+1)=nГ(n)
I am totally confused with it,so please help me through this...........
Just integrate by parts the expression:
$\displaystyle \int_0^{\infty}e^{-t}t^{s}dt$
Just let s be an integer for now.
Let $\displaystyle u=e^{-t};\quad dv=t^{s}$
Now, try and finish that and you should end up with an expression that can be put into the form $\displaystyle s\Gamma(s)$.
