In dealing with finding antiderivatives of integrals, first observe whether the integral is proper or improper as I didn't in klooless example below. Fortunately the improper integral converged, so no damage was done.
For example, if we blindly evaluate ∫−12x3dx, we get 83.
This is wrong, as the integral is improper (infinite discontinuity at x = 0) and the integral actually diverges.
Just a thought for what it is worth dept., as I am as guilty as the next person.
