The problem ask to find the value of the cos(infinity) and the best answer, base on my further calculation and formulation that came up to a solution that leads me to an answer that the cos(infinity) is undefined but it has a range of (-1,1). I hope you are satisfied with my answer and feel free to ask for more 

Any value between -1 to 1. The value will oscillate.

We know that the values of cos is always between -1 to 1.

Infinity is not a fixed number. So as the value of infinity changes then the value of cos will also change, but will stay between -1 to 1.
