Relationship between a sine-curve and the y-value of the unit circle
Context
This was a project as part of the Talking Maths in Public Animation Collaboration. The prompt for this one was
"Create an animation that shows the link between a sine curve and a unit circle (i.e. that the y-coordinate of a point on the circle is the sine of the angle to the x-axis at that point)."
