Explanation:

Answer 2

Answer with explanation:

The given trigonometric Function is,

y= cos x

→The maximum value of , cos x , is 1, at x=0 degree.

Cos x =1

→Cos x = Cos (0)degree,

`x=2 k \pi \pm 0`

→ for, k= An Integer

x=2 k π→→General formula that gives the x-coordinates of the maximum values for y = cos(x)

Ordered Pair =(x,y)=(2 k π, 1)

For, any value of , k in the given equation, y will be always 1.
