## Section 4.4: Applications of Sinusoidal Functions and Their Derivatives

**Key Concepts:**

- Periodic motion occurs in a variety of physical situations. These situations can often be modelled by sinusoidal

functions.

- Investigation of the equations and graphs of sinusoidal functions and their derivatives can yield a lot of

information about the real-world situations they model.
