Use a unit circle tool to explore cosine values in different quadrants. Determine the cos Ø values for angles between 0 and 2? radians. Observe the symmetry and patterns of the functions to predict the behaviour of cos Ø in different quadrants. Observe the graphs animate and visually connect them with the unit circle tool and table values. Extend cos Ø for angles beyond 2? radians. Find out how trigonometry relates to the real world. This learning object is one in a series of seven objects. Three objects in the series are also packaged as a combined learning object.
Objective
Students apply the unit circle definitions of the cosine function for angles expressed in radians.
Students interpret a graph of cos Ø, from 0 to 2? radians.
Students identify patterns and symmetry of the cosine function.
