I've almost gotten through this one integral problem, but i've seem to have gotten stuck:(adsbygoogle = window.adsbygoogle || []).push({});

integral ((sqrt(4-x^2))/x) dx

i let x = 2sin(theta), and dx = 2cos(theta)d(theta)

sqrt(4-x^2) = 2cos(theta)

integral ((2cos(theta))/(2sin(theta)) * 2cosd(theta)

2 integral cos^2(theta)d(theta)/sin(theta)

That's as far as I got, any suggestions?
