Trigonometry Interactive Unit Circle. An interactive for exploring the coordinates and angles of the unit circle, as well as finding the patterns among both. Compare the graphs of sine, cosine, and tangent.
Trig Tour Trigonometry Unit Circle Sines Phet Interactive Simulations from phet.colorado.edu Of course, there are lots more things the unit circle is used for, but we will get also note: In a circle or on a graph. Recall special right triangles from geometry.
The unit circle demonstrates the periodicity of trigonometric functions by showing that they result in a repeated set of values at regular intervals.
… but even better than this is the unit circle. · understand unit circle, reference angle, terminal side, standard position. Students will memorize the unit circle as they rotate special triangles and read the values of sine and cosine at different angles. Take a tour of trigonometry using degrees or radians!
