This is suppose to equal 2ln(2) but I am confused how I am supposed to solve this

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

I got to 2/u

Unclear what is written, I assume $\int_2^4\frac{2}{x\ln(x)}\dd{x}$, to which just $u=\ln(x)$

But then I get a weird long

I did that

wait

I forgot

Absolute value

[junior hamlet]

yeah, so $2\int_{\ln(2)}^{\ln(4)}\frac{1}{u}\dd{u}$ etc

[shrewd smelt]

No wonder my values when I did ln wasn’t working properly

Yup

Thank you sorry for the time waste
