is there any simple way to solve it ?
f(x)=6x/x^2-16

f''(x)=? i tried to find second derivate but it is too long

f''(x)=?   i tried to find second derivate but it is too long

anonymous · Answer

Maybe sometimes it take a long way

anonymous · Answer

but it is really long

anonymous · Answer

6x/(x^2-16)? so you got the denominator in 4th power?

anonymous · Answer

Wouldn't this be the same as the second derivative of 6/x ?

anonymous · Answer

i dont think so

anonymous · Answer

Unless it is 6x / (x^2 - 16) instead of 6x/x^2 - 16

anonymous · Answer

I guess it should be what he meant

anonymous · Answer

Ah ok.  Good luck :)  I do not see any shortcuts here.

anonymous · Answer

6x / (x^2 - 16)

anonymous · Answer

this is the func

anonymous · Answer

It's not so long, just the distribution take a bit time, I don't recommend you group into (a+b)(c-d) though. It would make it longer. But yeah, no particular short cut

anonymous · Answer

i see right now 16 different number to add or subsract on top side :)

anonymous · Answer

As expected, been there done that, and I hate this kind of derivative the most. Urg.

anonymous · Answer

it makes me feel stupid to try :) it looks like wrong but it is not

anonymous · Answer

im trying to sketch a curve i have to find second derivate of the func. and inflection points

anonymous · Answer

Partial fraction may help

anonymous · Answer

But it will make it simplier not short

anonymous · Answer

thx clearly there is not short way to solve :)

anonymous · Answer

It would help determine end behavior and asymptotes though
