CIRCULAR FUNCTIONS AND TRIGONOMETRY

:
(b) For -2zr 3 x ! 4r, sketch the graph of the tunction y cos x and y: cos 1x +41

on the same axes

Fory: cos (x + the maximum value is ......, the minimum value is
i),

the amplitude is , the period is

(c) For-a <x<7r, sketch the graph ofthe lunction y= tanxandy=tan(x- 1)
6'
on the same axes.

:
How does c affect the function y tan( x + c)?..............
Whal transformalion would move y :lanx to y :tan(x + c) ?
