Sine, Cosine Explorer
- Tom Ahlschwede
Use the Angle slider to move a point around a unit Circle. Watch as points are drawn to collect the angle measure with the x or y value of the point on the circle. What do you notice? Use the checkboxes to select Sine, Cosine, or both.
Is there a place where the sine and cosine traces cross? What is the domain? What is the range? Are they similar? Different? How do the traces compare? Do they have similarities? What happens for negative angle values?
