Use Trig spinner to learn the most important angles in the sine, cosine, and tangent functions. Download for Mac or PC. This application works much like flashcards for review. Click "Learn" for a quick view and "What is Trig?" to understand the basic premise of trigonometry. Identify the hypotenuse, adjacent, and opposite in order to use these as ratios to identify the sine, cosine, and tangent. Choose sets in 3, 6, 12, or 24. Change setting such as hints on or off, degrees or radians, and marathon sessions. Problem sets are shown in random. Use the information given to arrive at an answer. Click on your answer. Red X's appear when an incorrect answer has been chosen and a green O when chosen correctly.

#### In the Classroom

Teachers who must request software installation by tech staff may want to try this tool at home and create some examples to convince administration of its educational value. Use these "flashcards" for practice in determining the sine, cosine, and tangent of angles. Create posters of problem sets students create in order to provide additional practice. Use this site on an interactive whiteboard or projector to solve the problems, analyze the solutions as a class or group, and increase understanding by the students in the class. Consider listing this site on your class webpage for students to access at home for additional practice.
