# Moment generating function technique

If $X$ follows normal distribution with mean $\mu$ and variance $\sigma^2$, then the moment generating function of $X$ is given by: $$M_X(t) = e^{\mu t + \frac{1}{2}\sigma^2t^2}.$$

Then how can I find the pdf of $\dfrac{1}{X}$ using moment generating function technique?

Why do you want to use MGF to find the PDF of 1/X? –  Did Apr 28 '13 at 11:39
