On this interactive website students practice various math skills using a real-life scenario involving plants. Those skills include interpreting data in a circle graph, interpreting data in a divided bar graph, and interpreting a bar...

This tutorial walks students through how to create different types of graphs using the Create a Graph tool available on the website. Covers bar graphs, line graphs, pie charts, area graphs, scatter plots, and dependent and independent...

Detailed math tutorial features notes and examples that illustrate graphing circles.

A lesson plan where students will interpret the trigonometric functions in terms of the unit circle, graph a sinusoidal function, and use a sinusoidal function to make interpretations in a modeling context.

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....

This section explores the relationship between right triangles, circles, and trigonometry. It investigates how a right triangle that is set inside a circle and rotates around the circle is connected to trigonometric functions and their...

College professor Dan Bach reviews basic trig concepts, including trig functions, right triangles, circles, radians, and polar coordinates. Site includes animated graphs and detailed examples.

The Clark University site shows and explains the graphs of the six trigonometric functions. It explains how to find an arbitrary angle measurement using trig. Also, it explains that sine and cosine functions are complementary.

In this activity students will contribute a set of random points to a graph of a circle of radius 1 inscribed in a square. They will estimate the area of the circle using geometric probability.

In this task, a model airplane pilot is practicing flying her airplane in a big loop for an upcoming competition. The task could serve as an introduction to periodic functions and as a lead-in to sinusoidal functions. By visualizing the...

Data comes to the rescue! Children will collect, analyze, and represent data as they try to dodge a series of catastrophes faced by characters from their favorite PBS Kids shows.

The orbits of satellites are described and an energy analysis is performed. Kinetic, potential and total mechanical energy are explained and applied to the motion of satellites.
