I need help with this problem:
Consider the region R, bounded by y=-4cos(x) and y=2.
I can use either disks or shells to solve this problem.
I need help setting up the integral required to find the volume of the solid obtained by revolving the region R about the line y=1.
I think to set up this integral you would use this integral:
2PI∫from 2 to 4 (x-1)(-4cos(x)) using
I'm not sure if I've set this integral up right.Have I done something wrong? Thanks in advance to all who can help,
