This problem is from a book I have, and has three parts. I have attached both the problem (p23.jpg) and the solution (a23.jpg). I've tried different approaches, but I think I'm either not using the correct formula, or not setting up the integrals correctly. I'd appreciate someone showing me how to arrive at the solutions. Thanks for your help.© BrainMass Inc. brainmass.com March 4, 2021, 6:13 pm ad1c9bdddf
