While at the mall, you ran into your old friend, Tom, who is also taking a calculus course. What a coincidence. Tom is bragging about his integration skills and his scores on calculus tests. After exchanging email addresses, you say your goodbyes.

Subject: Integration Hi, Great to see you. I'm working on my calculus homework and trying to solve these integrals Sac2(x3 + 1)? dac fev5 + edx Ssin(1) cos (")dx dax x - V They are kind of tricky! I'm not sure you can solve these! TomPart A When you calculated the integral for f x2 (x3 + 1) dx, was one method better than the other? Explain.Part B When you calculated the integral for f 631/5 + emdm, was one method better than the other? Explain. Part C When you calculated the integral for Is in () co 3 (%)d:v, was one method better than the other? Explain.
