Please help with solving and unterstanding this integral
For problems 1 and 2, set up volume integrals using both cross-section method and cylindrical shell method. Then pick one method to solve. If you evaluate both methods and show they are equal, you can get up to 5 points extra credit per problem. 1) The region bounded by y = Inx, y = 0, and x = e, rotated around the x-axis.
