question:

ln(x^2)/ln(e^x)

I just don't see anything on the formula sheet that matches this.

I assume you wish to integrate this expression?

integration by substitution ...

let

can you finish? - Jan 5th 2013, 01:59 PMPlatoRe: help with natural logarithm

**I**don't see a question! You give an expression. What do you want to do with it? If you are trying to "simplify" it then two basic properties should help: and [tex]ln(e^x)= x[/itex].

You give a link to a "list of integrals". Do you want to integrate that? ? Then I think the substitution u= ln(x) will do nicely! - Jan 6th 2013, 08:53 AMtogoRe: help with natural logarithm

yeah I have no idea where to find the rule for handling that. It didn't look like it was on the wikipedia formula sheet.
