And the upper bound is 2 and the lower bound is 0.
I split the integral into two separate integrals and I was able to solve the second part (pi(exp(x))^2) but I was told by another math tutor that the first integral couldn't be solved by rules of integration, but instead by estimation. She said simpson's rule would be best, but I thought we needed an "n" to solve for that...and even then I'm not quite sure I understand what she meant. Help!
Thanks a lot!
