st: Integrals

["Jann Ben" <ben.jann@soz.gess.ethz.ch>]

Hi, I am interested in evaluating integrals of

 x^r * f(x)

and

 f(x)^2

from minus infinity to b, where b < infinity.
r is a positive integer and f(u) is the standard 
normal density.

Is it correct that such integrals can only be 
solved via numerical integration and that they
cannot be expressed in terms of normal() and 
normalden()?

Thanks,
ben
