(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

evaluate the integral cos^-1 2x dx?

2. Relevant equations

3. The attempt at a solution

let

u = arc cos

du = -1 / (sqrt 1-x^2)

dv = 2x

v= x^2

arc cos * x^2 - the integral of -x^2 / (sqrt 1-x^2)

then i don't know what to do
