TLF ID L7849
Use a unit circle tool to explore sine values in different quadrants. Determine the sin Ø values for angles between 0 and 2π radians. Observe the symmetry and patterns of the functions to predict the behaviour of sin Ø in different quadrants. Observe the graphs animate and visually connect them with the unit circle tool and table values. Extend sin Ø for angles beyond 2π 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.
