Unit Circle beyond 0 and 2pi
- Anthony Odeh
Here is a unit circle that extends beyond the angles of -2pi and 2pi. This file allows the user to change increment in which the angle is measured for the sine and cosine. The check boxes plot the sine and cosine of the given angle on the grid on the bottom of the page, and the "direction slider" allows the user to use positive or negative angles. This can be extended to the other trigonometric functions (secant, tangent, cosecant, and cotangent). I hope this file helps you teach your students all about the unit circle!
