## Course Description

This course is a continuation of the theory of integrals from calculus 1. So we begin this course with several applications of the integral. First up is the area between curves. We motivate and prove theorems that give us the flexibility of finding areas from different viewpoints. In doing so, we work through several examples that demonstrate each strategy.

After finding areas, we continue with finding volumes. We begin by explaining solids of revolution and then walk through (in detail) several methods for find volumes, including using disks, washers, cross-sections, and cylindrical shells.

We then turn to arc length and its generalization: areas of surfaces of revolution. We motivate these concepts and work through several examples and applications. In detail, we examine work, fluid pressure and force, and moments and center of mass.

At the end of this course, we study hyperbolic functions and some applications. We give a thorough treatment by defining these functions, examining their graphs, exploring fundamental identities, proving derivative formulas and derivative formulas of their inverses.
