Look sin and cosine are periodic functions , periodic functions mean that the final value of the function for any value of x is only between a confined range , and for sin and cos function their range comes out to be [-1,1] for any value of x.
So, this means obviously even at x = Infinity , the final value of sin x and cos x would come out to be something between -1 and 1.
However, we don't know the exact value because even infinity is not defined so we actually don't know what value of x has to be put In exactly !
Periodic functions actually mean that when you draw them on graph, their graph is continuous at every point at changes it's slope at regular intervals to give same value for values of x repeating after some interval.
I recommend you to read more about period of functions.
Hope this helps you !
