CIRCUT,AR FUNCTIONS AND TRIGONOMETRY

2. Functions of the form y = sin bx,y = cos bx and y = tan bx

(a) For-2zrSxS 42, sketch the graph of the function y - sinx and y: sin 2x on the
same axes

For y: sin 2x, the maximum value is ._...-....and the minimum value is
the amplitude is and the period is

(b) For-22 3xS4tr, skctch the graph ofthe fi-urction y-cosxandy=cos lxonthe

same axes.
