Question

Graph two complete cycles of each of the following functions. a. f(x) = cos(x) – 2 b. g(x) = sin(x -
`(\pi)/(2)`

Answer 1

Ok, to graph this

The purple curve is the curve of

`g(x)=\sin (x-(\pi)/(2))`

The orange curve is the curve of

`f(x)=\text{ cos(x) -2}`

2. You observe that

`\sin 60^{0^{}}\text{ = sin}(\pi)/(3)`
