TRIGONOMETRY FUNCTIONS

TRIGONOMETRY FUNCTIONS. OF GENERAL ANGLES. Our method of using right triangles only works for acute angles. Now we will see how we can find the trig function values of any angle. To do this we'll place angles on a rectangular coordinate system with the initial side on the positive x -axis.
