Best ResponseYou've already chosen the best response.1hint: let u = ln(x) and let dv = 1 dx

Best ResponseYou've already chosen the best response.0@Christos xlnx is not the answer. Use integration by parts

Best ResponseYou've already chosen the best response.1if you are just guessing you can go to wolframalpha and get the answer

Best ResponseYou've already chosen the best response.1I am not guessing I though x has a power of 1 so 1 at the end and outside of ln whatever is inside

Best ResponseYou've already chosen the best response.1it is like the inverse of that, it is how we undo that rule.

Best ResponseYou've already chosen the best response.1I would google it and read on it, it takes practice

Best ResponseYou've already chosen the best response.1do you know u substitution for integration?

Best ResponseYou've already chosen the best response.1ok that "undoes" the chain rule, so now you need to learn by parts. there are both crucial to learning integration http://tutorial.math.lamar.edu/Classes/CalcII/IntegrationByParts.aspx

Best ResponseYou've already chosen the best response.1e^(2*lnx) = e^ln(x^2) = x^2 so you need the integral of x^2 not ln(x^2)

Best ResponseYou've already chosen the best response.1I solved it now :D I know how to find this thing very easy (x^3)/3 without any actual formula
