I kind of asked this question before, but in a more confusing context,
so now I would like to ask it by itself.
In the course of my computations, I get Abs' and Abs''. It is applied to
a positive number, so I think those values should be 1 and 0. However,
Mathematica fails to simplify it.
These expressions really mess up my answers. How do I get Mathematica to
do these simplifications?
