Below

#### Explanation:

where:

a = amplitude

So we know that its amplitude is 1

the period is:

and we shift the equation to the right by

Below is the graph

graph{cosx [-10, 10, -5, 5]}

Now, this equation needs to be shifted to the right by

Below is the graph

graph{cos (x-pi/4) [-10, 10, -5, 5]}
