Outcomes

12F.B.1.1

Recognize the radian as an alternative unit to the degree for angle measurement, define the radian measure of an angle as the length of the arc that subtends this angle at the centre of a unit circle, and develop and apply the relationship between radian and degree measure

12F.B.1.2

Represent radian measure in terms of p and as a rational number (e.g., p/3 radians, 2p radians) (e.g., 1.05 radians, 6.28 radians)
