Volume Calculation Using the Shell Method

The video tutorial explains how to calculate the volume of a solid formed by rotating a region bounded by the function y = e^2x + 1 around the y-axis. The shell method is used for this calculation, involving setting up an integral with respect to x. The tutorial details the process of integration by parts to solve the integral and find the volume, which is approximately 8.2495 cubic units.

What is the function that defines the boundary of the region to be rotated?

• y = e^2x + 1

• y = e^x + 1

• y = e^x - 1

• y = e^2x - 1
