differentiate is a general differentation operation It must fulfill the Leibnitz condition

   differentiate (x * y) == differentiate x * y + x * differentiate y

Unfortunately, this scheme cannot be easily extended to more than two variables, e.g. MathObj.PowerSeries2.

differentiate :: a -> aSource
