Best ResponseYou've already chosen the best response.0\[\int\limits_{1}^{2}1/(x(3+x^2)^(1/2))\] let u = 3+x^2 du= 2xdx (1/2)(1/u)^(1/2)]du (1/2) 2u^(1/2) =u^(1/2) when x = 1 u =4 and when x = 2 u = 7 therefore =7^(1/2)2^(1/2)

Best ResponseYou've already chosen the best response.11/(x sqrt(x^2+3)) substitute x = sqrt(3) tan(u) and dx = sqrt(3) sec^2(u) du. which is why i didnt want to do this one, lol
