Key Radian Values on the Unit Circle

Key Radian Values on the Unit Circle

This program provides practice thinking in terms of radian measure.  Students can click on wedges of size pi/6, pi/4, pi/3, or pi/2 to move around the unit circle and land on the key values that all trig students need to learn.  This program is appropriate for students who already know what a radian is, but need some practice working with radians.  Students also should have already learned the key value on the unit circle, but they can practice locating where those values are at with this program.  Students do not need to know the definition of the six trig functions to work with this program, but if your students already know those definitions, you can easily add some questions about the trig functions as they are working with the program. trig, unit circle, radian measure, math, precalculus, trigonometry
