But often, it comes with some other bells and whistles. A unit circle defines right triangle relationships known as sine, cosine and tangent. These relationships describe how angles and sides of ...

Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations ...

Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs of sine and cosine are related to the unit circle. Transformations of Functions 1.3 An applet illustrating how transformations ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around ... depending on the value of \(\theta\). The graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) ...
