You forget dx in the integral (very important. You need it to the change of variable)

Let y=ln(x+1)

dy=dx/(x+1) - Aug 1st 2013, 08:28 AMPlatoRe: Integration

No, you won't be "given a solution", but you can be given some hints. First of all, having "x + 1" in both the numerator and denominator makes things look convoluted. So a substitution would clean things up a bit, giving

Now notice that is the derivative of , so a substitution of the form is appropriate, giving

Surely you can integrate THAT.
