Well, what function has a derivative of 1/x? You already have 1/x therefore, you need to find the antiderivative of it. This is ln(x).

Oh i see, thanks.
Another qu, what is the integral of 1/x dx ?
I know its something like y = loge x or something (not sure what it is exactly) but i dunno why.. First of all, what is e. I know its used heaps in logs, but its just some number originating from an infinite series of 1/1 + 1/2! + 1/3! ... etc but what advantage does it have in terms of logs? and umm, yeah, the integral question. How does 1/x become loge x?
