[Free Registration/Login Required] Students describe, analyze, and reason angles being as small or as large as they can imagine. Using trigonometrical ratios, this is a fun exercise in understanding how to examine the perfect graph.

[Free Registration/Login Required] This flipchart shows the basic relationships between trig functions and the sides and angles of a right triangle.

[Free Registration/Login Required] Students will use a number of strategies (including Algebra II and properties of conjunction techniques) to find all solutions for trigonometric equations using multiple angles.

[Free Registration/Login Required] Students explore trigonometric functions using the interactive features of Activstudio. Students apply their understanding of trigonometric sense to determine the side lengths and angles of various...
