## Homework Statement

I have a problem, I don't know how to find the limit (cos(Pi/2x))^2x when x is ∞

## Homework Equations

(1+(1/x))^(1/x)=e

## The Attempt at a Solution

I have been looking for solutions on the internet, but most of these just tend to be for fractions, I don't know how to operate with a cosine.

Any help?
