Trig degrees: cosine to 360

Learning Material  |  Interactive Lesson


Published on 2018 August 13th

Description
Use a unit circle tool to explore cosine values in different quadrants. Determine the cos Ø values for angles between 0° and 360°. Observe the symmetry and patterns of the functions to predict the behaviour of cos Ø in different quadrants. Observe the graph animate and visually connect it with the unit circle tool and table values. Extend cos Ø for angles beyond 360°. Find out how trigonometry relates to the real world. 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 apply the unit circle definitions of the cosine function.
Students interpret a graph of cos Ø, from 0° to 360°.
Students identify patterns and symmetry of the cosine function.
