Watch a demonstration showing how cosine is defined in the unit circle. Connect this definition with the right-angled triangle definition commonly used in right-angled triangle trigonometry. This learning object is one in a series of nine objects. Three objects in the series are also packaged as a combined learning object.
Objective
Students view the unit circle definition of the cosine function.
Students view the connection between the unit circle definition of cosine and the right-angled triangle definition of cosine.
