QUIZ 2
Sketch and label an accurate graph of the bounded region for each volume problem below, highlighting your slice. Make sure all answers have the proper units. 1. Set up an integral that uses the disk method to find the volume of the solid of revolution obtained by revolving the area between the curves y = sech(x/2), y =2, x =0 and x = 4 around the line y=2. Include a sketch of the region and show all work to integrate and. Note:Recall that sech(u) = 1/cosh(u).
