What is the period of the parent cosine function, y = cos(x) in degrees?

Period of y= cosx is 360°

Step-by-step explanation:

Refer the figure given below.

The period is the time required to complete one revolution.

We have graph for y = cosx.

We can see the function is repeating after a change x axis value of 2π.

That is the period of y = cosx is 2π.

Here 2π is in radians corresponding degree value is 360°

So period of y= cosx is 360°
