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?

Question

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

mendicant_bias · Answer

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

mendicant_bias · Answer

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

mendicant_bias · Answer

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

mendicant_bias · Answer

Nope, nevermind, don't got it.

pull out x^4 from the denominator

ganeshie8 · Answer

then u may see wat to sub

mendicant_bias · Answer

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

mendicant_bias · Answer

(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/)

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

ganeshie8 · Answer
