# Is there such a thing a literaly integrating ln x? Watch

1. Hi there

Is there such a thing a literaly integrating ln x?
2. Yes, it is .

You can find it using integration by parts.
3. Yup. choose, as JB says, parts, using Ln(x) = Ln(x) x (1) - derive the Log part, integrate 1 for the other
4. How do you figuratively integrate a function?

Hi there

Is there such a thing a literaly integrating ln x?
I'm gonna take a guess and say you've got a C3 exam 2morrow.
You should avoid integrating Ln X, that's why in integration by parts you make u=Ln x no matter what that way you only have to differentiate it and not integrate it.
This method works because i tried it with a question and came out with the right answer.
6. Here is an example from my book:

Eh?

NO!

Eh?

NO!
well your question said "literally" and dont really know what you mean by using that word in this context?
9. xln(x) - x + c
10. It could be a misspelling of "illiterately".
11. On a more serious note - the posters who gave the answer are correct, but you should try it yourself. Integrate by parts, using the trick . It may seem weird, but it works.
