I am new to bayesian and random variables. How do I find the mean and the variance of this distribution. The distribution is $$f(x|\gamma\ ^2) ∼ \gamma\ ^{(N-1)/2} e^{(-x^T\delta\ x )/2 \gamma\ ^2} $$
I know that we need to integrate according to x to find the mean but how do we integrate $-x^T\delta\ x $. Any help would help.
