Interactive graphs of trigonometric functions and the Unit circle

Features & Capabilities

This Chrome extension offers an educational tool to master the core concepts of the Unit circle and trigonometric functions through interactive graphs. Users can move points on the unit circle to observe angle changes (in degrees or radians) and their effects on sine and cosine values.

Key features include: interactive graphs for visual understanding, comparison of trigonometric function graphs, detailed function descriptions, the ability to explore how parameters influence graphs, tables of values for special angles, comprehensive trigonometric formulas and identities, and quizzes to reinforce learning. Additional trigonometric functions will be added soon. For support or inquiries, contact stalulerlan@gmail.com.
