The problem ask to find the integral of the trigonometric equation of arcos x/qrt(1-x^2)dx and the best answer that i could give base on the given equation and my further computation and that is <span>∫arccos(x)/sqrt(<span><span>1−<span>x2</span></span></span>dx)=1/2(arccos(x)<span>)2</span>+c. I hope are satisfied with my answer and feel free to ask for more </span>
