## Mendicant_Bias Group Title 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? 7 months ago 7 months ago

1. Mendicant_Bias Group Title

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

2. Mendicant_Bias Group Title

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. Mendicant_Bias Group Title

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

4. Mendicant_Bias Group Title

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

5. Mendicant_Bias Group Title

Nope, nevermind, don't got it.

6. ganeshie8 Group Title

pull out x^4 from the denominator

7. ganeshie8 Group Title

then u may see wat to sub

8. Mendicant_Bias Group Title

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. Mendicant_Bias Group Title

(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 Group Title

its not working from two days

11. Mendicant_Bias Group Title

This is happening to everybody?

12. ganeshie8 Group Title

nope, oly for some priviliged users...

13. Mendicant_Bias Group Title

Will do drawing tool. Ah.

14. Mendicant_Bias Group Title

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

15. ganeshie8 Group Title

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

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

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