A short interactive activity to visualize the trigonometric functions: sine, cosine, and tangent.

This lesson defines and explains hyperbolic functions. It has graphs and examples for the student to examine.

In this TI InterActive! activity, students study the phases of the moon, plot the fraction of the moon showing each day in a month, and fit the data with an appropriate trigonometric function.

In this activity, students explore the properties of a unit circle and its mapping functions.

The students will discover the shape of the sine function without creating a t-chart. The students will create a sine function using toothpicks. The students will then discover how the amplitude (height) and the period (number of compete...
