Trigonometric Functions Teacher Resources

This lesson explores the relationships between triangles made on a unit circle and the six trigonometric functions. It is 1 of 5 in the series titled "Triangles in the Unit Circle."

Two hands-on lab activities for instructors to use when teaching about the coordinate graphs of the sine, cosine, and tangent functions derived from a unit circle. The graphs of the reciprocals of the three functions are investigated....

Given a sine, cosine, or tangent value, find the principle angle that has this value. In other words, find the arcsine, arccosine, or arctangent of that value. Students receive immediate feedback and have the opportunity to try questions...

The video from Khan Academy provides practice questions for the SAT. Students will watch Sal work through a basic angles, arc lengths, and trig functions problem.

The video from Khan Academy provides practice questions for the SAT. Watch Sal work through a harder angles, arc lengths, and trig functions problem.

Given the graph of a sinusoidal function, determine its period. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this section we will give a quick review of trig functions. We will cover the basic notation, relationship between the trig functions, the right triangle definition of the trig functions. We will also cover evaluation of trig...

Analyzing the amplitude and periods of the sine and cosine functions.

Students can watch a short video to review using the tangent for trig substitution.

Solve equations of the form sin(x)=d or cos(x)=d where d is any number. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
