Two templates to turn your school clock into a unit circle.
And here is another:
Some wonderful animations that show the sine, cosine and tangent of angles on the unit circle.
This animation from Lou Talman shows how a point moving around the unit circle generates the tangent function.
This Quicktime animation from Lou Talman shows how the sine curve can be constructed from the definition of the sine function as the y-coordinate of a point on the unit circle.
Mad Minute activities are warm-up and review activies. This one reviews the exact trig rations. Drag in the stickies as visual aids.
