Sine and Cosine GraphsA highly effective interactive animation illustrating the sine and cosine graphs formed by rotating a point around the unit circle.
Transformations of the Sine CurveThis interactive animation shows the effect of adding a constant to the function. This interactive animation shows the effect of multiply the function by a constant a where a >= 0. This interactive animation shows how altering b in the function
The Ambiguous Case of the Sine RuleThe powerpoint is digital and the activity is interactive. The two powerpoints are very well done - clear and profesional looking. The activity is nicely thought-out. Great job, Pam! Powerpoints Activity Sheet
The Unit Circle and the Tangent FunctionThis animation from Lou Talman shows how a point moving around the unit circle generates the tangent function.
The Unit Circle and the Sine CurveThis 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.
The Unit Circle and the Graph of the Tangent FunctionThis animation from Lou Talman shows how a point moving around the unit circle generates the tangent function.
The Unit Circle and the Graph of the Sine FunctionThis 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.
Sine and Cosine FunctionsA lovely Geogebra applet that graphically shows how the sine and cosine functions are generated from the unit circle. From The Lawrenceville School Mathematics Department Web Resources.
Mad Minute - Exact Trig RatiosMad Minute activities are warm-up and review activies. This one reviews the exact trig rations. Drag in the stickies as visual aids.
