Hi All,

I am working on some integrals involving the Normal Distribution, and would like the end results to be expressed in normal density as opposed to the Erf[] function.

For example, the default result of the following:

Integrate[PDF[NormalDistribution[0, 1], x] Exp[x], x]

is

1 -1 + x
- Sqrt[E] Erf[-------]
2 Sqrt[2]

I'd like it to be in terms of CDF[NormalDistribution[]].

Is there any way to do that?

Thanks,
Irving.
