CIRCULAR FUNCTIONS

This video was done by a teacher in Victoria and explains how to do the questions in Ex 6J: Finding the equation of a circular function from its graph. 

This video was done by the same teacher and explains how to solve the questions in Ex 6C and Ex 6D using the Symmetry Properties
