Homework Statement
I was doing a statistics problem, and ended up with this integral:
∞
∫ [1/(2pi)] [e-(w2+z2w2)/2] |w| dw
w=-∞
How can I evaluate this?
Homework Equations
The Attempt at a Solution
1) How can we integrate |w| (with the absolute value)?
2) What should we do with the z? Can we treat it as a constant here?
3) Do we need integration by parts here? If so, what should u and dv be? Looks like the thing has no antiderivative...
Thanks for helping!
