Complete the general solution to y=cos^-1(1) for k a whole number

If the equation is exactly the one you posted then the unique answer is:

or  what is the same:

Explanation:

If your equation is exactly the one you posted then it has only one solution: y = 0

Because the range of is the interval

The meaning of is to find the angle whose cosine is 1.

In the range of the function arccosine the only angle whose cosine is 1 is the angle 0.

But if your equation was the following one:

Then in that case we would have infinite solutions since it will be the set:

 where K is an integer, since the period of cosine is

So, in such a case the solution set would be:

But for the equation you posted, the unique solution is: y = 0 or what is the same y = 0K
