## anonymous 2 years ago I found a particularly ugly indefinite integral that I can't seem to figure out how to evaluate (technique used is supposed to be u-substitution). Anybody care to take a gander?

1. anonymous

Ugh, I'm not able to pull up the equation editor.

2. anonymous

The integrand is: sqrt((x^3 + 3)/x^11). Supposed to figure out how to deal with that via u-sub. @hartnn , any clue?

3. anonymous

Correction, -3, but that shouldn't really matter in this case.

4. anonymous

I think I just maybe, heh...lol, keep going, but I think I'm figuring something out

5. anonymous

Nope, nevermind, don't got it.

6. ganeshie8

pull out x^4 from the denominator

7. ganeshie8

then u may see wat to sub

8. anonymous

One sec, trying to figure out if I can get the eqn editor to work so I can show what I'm exactly doing

9. anonymous

(Nope, still not able to get it to work, but thanks for the moment, just trying to figure out why I can't get the LaTeX editor working/)

10. ganeshie8

its not working from two days

11. anonymous

This is happening to everybody?

12. ganeshie8

nope, oly for some priviliged users...

13. anonymous

Will do drawing tool. Ah.

14. anonymous

Looks like I'm not able to use the drawing tool, either, lol...

15. ganeshie8

yes both drawing+latex became buggy from two days for many users

16. hartnn

$$\Large \dfrac \int \sqrt{x^3-3}{x^{11}}$$

Lol I actually opened TeX Studio and started manually typing it up, but twiddla is fine
