Sinusoidal Functions and Population Modeling

The video tutorial introduces sinusoidal modeling, focusing on practical applications. It begins with an analysis of a wheel problem, deriving a sinusoidal function to model the wheel's motion. The tutorial explains how to graph the function and derive its equation, followed by solving additional questions using the equation. Another problem involving fox population is explored, demonstrating the versatility of sinusoidal modeling. The video concludes with encouragement for further practice.
