103 - Stochastic Modelling Sept 2000 exam Q10 ii)
How has this integral been evaluated? I Can not follow these "tricks" that have been used here. I'm guessing by the looks of it the solution is equating the desired integral with the cumulative density function of a normal random variable with standard deviation 1/sqrt(mu)?
Seems to be a very elaborate piece of algebra because usually that integral would require a transformation to polar coordinates.
