Exploring the graph of the Sin function and the unit circle
- Michael Andrejkovics
This applet will allow you to explore the geometric meaning of the sin curve. Play around with the amplitude and frequency sliders to see how it affects the circle, and the resulting sin curve. Hit the play button in the bottom left to animate the point and see it travel around the circle.
How does the amplitude affect the curve and the original circle? How does the frequency affect the curve and the original circle?
