I am trying to build a rule for manual integration. I want to test
whether an expression matches the general form:
c (e + f x)**p
where c, f, and p can be non-zero expressions not containing x, whereas
e can be zero but again cannot contain x.
Moreover, if the expressions matches the above form, I would like to
parse it such that I know the values for c, e, f, and p.
Any suggestions on general strategies for achieving my goals? I have
been thinking about prolific use of func and args. I imagine that I
would consider various branches for my test since c = 1, e = 0, f = 1,
and p = 1 would all change the class type of the expression or
sub-expressions.
