simple integrals

About simple integrals with a bunch of constant forefactors and the
comment by Pekka Janhunen concerning a preprocessor:

In my original post I included a one-liner which does a similar thing.
I applied the differentiation operator D to all parts of the expression
and pulled the factors out which evaluated to zero. Even with this
extremely stupid and simple method the integration was orders of magnitudes
faster!!
