The indefinite integral value at the given point. I.e., if `F(x) =
integral(f(x),x)` then `F(a) = sympy.Integral(f(x), x, a)`.
> Maybe Maxima has something like this that we already translate for them?
Couldn't find such a thing.
> Do you think there is a way to deal with this by raising an error upon
translation back to Sage (if that's appropriate)? Sorry for the
questions; each software has a slightly different philosophy.
Computation would be 1. compute the indef. integral; 2. if succesful
substitute. So not difficult I guess.
