Trig Tour 3 - Connecting the Unit Circle with a Graph

· Easily translate between multiple representations of trig functions: as sides of a right triangle inscribed in a unit circle, graph of the function vs. angle, and numerical values of function. - Deduce the sign (+, -, 0) of trig function for any given angle without a calculator using the unit circle concept. Based on PhET lesson Connecting the Unit Circle with a Graph by Susan Miller. https://phet.colorado.edu/en/simulation/trig-tour (> For Teachers for the paper lesson plan) (Image from Simple Wikipedia https://simple.wikipedia.org/wiki/Ferris_wheel)
