comment Calculus question that is driving me nuts. Rotation volume.
@Guinea You should simply leave the answer in terms of $\pi$ after your computation. Your web app most likely needs exact answers as opposed to numerical approximations. Leave your answer as $\frac{114\pi}{7}$.

coursera had a great functional analysis class taught by a French Professor (Lectures were in English). Unfortunately they have take it down since the course is complete. :(

Yes you are right.typo.

Well the integral is the 'signed area under the curve'. So if you evaluate from $a$ to $a$ the area (integral) is zero.
