The indefinite integral of sin^-1(x) or arc sin (x) divided by the square root of 1-x^2. All I can say is I have no idea what to do with this, I've never really worked with arcsin, I looked up derivatives and it doesn't seem like I can make one part of the equation's derivative cancel out another so I don't know if substitution would be a good route here. Could somebody help me out???
