Best ResponseYou've already chosen the best response.0is that (1x)/(x^2+1) or (1x)/x^2 + 1 ? for the first I would break it up into 1/(x^2+1) and x/(x^2+1) and integrate, the first term: arctan(x) the second: .5ln(x^2+1) from integral tables. for the second, put into the form eliotargy has above and integrate to (1/x)ln(x)+x. dont forget the constant of integration
