Explains the horizontal forms of trigonometric graphs by showing how they relate to the circular graphs.

Provides an explanation, examples, and a video lesson all related to trigonometric identities. [2:31]

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis...

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...

The purpose of this task is to help students make the connection between the graphs of sin t and cos t and the x and y coordinates of points moving around the unit circle. Students have to match coordinates of points on the graph with...

In order to determine how effective solar panels would be at various times of the year, it is important to know the amount of daylight at a given location. Students are asked to find an appropriate function that serves as a mathematical...

The purpose of this task is to use the notion of similarity to define the sine and cosine of an acute angle. Aligns with G-SRT.C.6.

[Free Registration/Login may be required to access all resource tools.] Find the amplitude of a sine or cosine curve.

Understand how trigonometric functions can model periodic behavior. See the application of periodic behavior, amplitude, frequency in sound waves. Make sure to turn up your sound to load an audio file to play the given tone of the...

An introduction to solving trigonometric equations, including finding general and particular solutions. The connection between the tangent function and the slope of a line is also covered. Includes several examples and graphs.

In this task, students investigate how many coins will fit around a central coin when they are all of the same denomination, and if there is room left over. The teacher is given a chart of four coin denominations and their diameters, but...

This task models a satellite orbiting the Earth in communication with two control stations located miles apart on Earth's surface. Learners determine distances between various locations and, given a rate of travel, they determine the...

For this task, young scholars are asked to calculate the height above sea level of a lamp on top of a lighthouse that is visible to a boat, and to examine two other interpretations of the distance from the lighthouse to the boat. Aligns...

A complete high school Precalculus Concepts course. Includes 'Related Modalities' for each lesson that teach the same concept in different ways. The text materials follows Algebra II and comes before Calculus or Statistics. The content...
