TLF ID L7843
Use a unit circle tool to explore sine, cosine and tangent values in different quadrants. Determine the values for angles between 0° and 360°. Observe the symmetry and patterns of the functions to predict the behaviour of the graphs and the values for the functions in different quadrants. Observe the graphs animate and visually connect them with the unit circle tool and table values. Extend the functions beyond 360°. Find out how trigonometry relates to the real world. This learning object is a combination of three objects in the same series.
