Best ResponseYou've already chosen the best response.0look at a quotient rule observe if \[f(x) = e^{x}\] and \[g(x) = x +1\] so that \[h(x) = f(x)/g(x)\] if you take the derivative of h(x) you will get exactly what you have. then just rewrite it as \[\int\limits (e ^{x}/(x+1)) d/dx\] and integral negates the derivative and you have the answer plus a constant of integration C
