Ferris Wheel Motion and Functions

The video tutorial covers a Ferris wheel problem, explaining how to model it using sinusoidal functions. It discusses the parameters of the Ferris wheel, including its diameter and vertical shift, and guides students through sketching the sinusoidal curve. The tutorial explains the concepts of period and amplitude, and helps students decide between using sine or cosine functions. It also demonstrates graphing the function using Desmos and calculators, and finding intersection points to solve the problem.

What is the diameter of the Ferris wheel discussed in the problem?

• 80 feet
