Ferris Wheel is one of the most popular application problems in trigonometry. It illustrates beautifully the relationship between a unit circle (or a circle), the graphs, the equations. It lets students use their calculators and see relationships between different trigonometry concepts.

The problem statement can be found HERE. And the solution is below.

When we know parent functions such as trigonometric, exponential or power functions, it is easy to draw their transformations using shifts, stretches and reflections. In this video I show an example of such transformations.
