Graph two complete cycles of each of the following functions. a. f(x) = cos(x) – 2 b. g(x) = sin(x - [tex] \frac{\pi}{2} [/tex]

Ok, to graph this
The purple curve is the curve of
[tex]g(x)=\sin (x-\frac{\pi}{2})[/tex]The orange curve is the curve of
[tex]f(x)=\text{ cos(x) -2}[/tex]2. You observe that
[tex]\sin 60^{0^{}}\text{ = sin}\frac{\pi}{3}[/tex]
