The given Trigonometric function is

y = Cos (x)

As the maximum value of Cosine (Theta) is 1. i.e

Maximum value of Cos (x) = 1

Cos (x) = cos (0 or 2 π)

If Cos (x) = Cos A

Then General formula for evaluating x is ,

x = 2 n π [tex]\pm[/tex] A, for n =......-3,-2,-1,0,1,2,3,4,5.....

Here, A= 0, so the value of x is =2 n π [tex]\pm[/tex] 0

x= 2 n π

For a cosine function, the minimum value is -1 and the maximum value is 1.

The formula is used to find the value of y = cos(x) is [tex]\rm x=2k\pi \pm0[/tex].

We have to determine

What formula gives the x coordinate of the maximum value for y=cos(x)?

What is the maximum value of the trigonometric function?

These two functions have minimum and maximum values as defined by the following formulas.

The maximum value of the function is M = A + |B|.

For a cosine function, the minimum value is -1 and the maximum value is 1.

The formula is used to find the maximum value of cos(x) is;

The maximum and minimum value of cos(x) is 1 and −1.

So cos(cos(x)) at x=90 is cos0=1(maximum value).

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

Cos x =1

Cos x = Cos (0)degree,

The cosine function oscillates between -1 and 1 that is the minimum value of cosine is -1 and the maximum value is 1.

We also know that cos(0) = 1 and after a period of cosine is 2π.

Therefore,

The formula is used to find the value of y=cos(x) is;

[tex]\rm x=2k\pi \pm0[/tex]

Hence, the formula is used to find the value of y=cos(x) is [tex]\rm x=2k\pi \pm0[/tex].
