Freddy the Frog Follow Up: Exploring the Graphs of Trig Functions

A follow up to Freddy the Frog, we consider what happens when the Water Wheel (unit circle) gets larger or smaller (amplitude change), when the Wheel speeds up or slows down (period change), and when the Centre of the Wheel moves up or down (vertical translation). Finally as an extension, Cosine is introduced at the end. This activity is in Degrees Original Freddy the Frog Activity: https://teacher.desmos.com/activitybuilder/custom/5f95f16e9e067e0c268e36f4
