Unroll the Circle, Get the Wave
You'll learnto unroll a point going around the circle into the sine wave.
A point rides counterclockwise around a circle of radius 1. Carry its height out to the right as the angle grows and the sine curve draws itself; carry its across instead and you get cosine. Twelve short steps; press Next for each one.
the circle is the definition, the wave is the recording
Before you start
What you're looking at
A point riding a circle of radius 1, and an empty pair of axes waiting beside it.
The question
As the angle grows, what does the graph on the right end up recording?
