- Homework Statement
- Essentially - find <1/x>, i.e. the mean of 1/x. The distribution probability density is of the form exp(-ax^2).

- Relevant Equations
- Mean of G = integrate ( G f(x) ) dx

Hopeless. I tried to use Taylor expansion but the zeroes and infinities go out of control really quick.

I tried WolframAlpha and it gave a special function.

What integrating trick am I missing? Or is it nonsense to solve it simply by hand?
