Modeling Heights and Temperatures

The video tutorial explains how to model the height of a rider on a Ferris wheel using a sinusoidal function. It begins with a sketch and graph of the Ferris wheel, then derives the equation for the height as a function of time. The tutorial also covers solving for specific heights and times. Additionally, it includes an example of modeling temperature changes over a year using sinusoidal functions.
