Math 138 – Fall 2011 Assignment 3 Due Friday October 7 (in the drop box by 12 noon) Hand in the following: 1. The curve f ( u ) = e u - u 4 - 1 has two roots u = 0 and u = b ( b > 0). Find the volume obtained when the region in the first quadrant bound by the curve x = e y - y 4 - 1 is rotated about the x -axis. You might want to use some plotting software to get an idea of the curve. Your answer should be in terms of the roots of
