jimthompson5910 (jim_thompson5910):

were you able to find dy/dx ?

OpenStudy (anonymous):

yes, I have the prime derivative I got -3x/y

jimthompson5910 (jim_thompson5910):

correct \[\Large \frac{dy}{dx} = \frac{-3x}{y}\]

jimthompson5910 (jim_thompson5910):

Now apply the derivative to both sides \[\Large \frac{dy}{dx} = \frac{-3x}{y}\] \[\Large \frac{d}{dx}\left[\frac{dy}{dx}\right] = \frac{d}{dx}\left[\frac{-3x}{y}\right]\] \[\Large \frac{d^2y}{dx^2} = ??\]

OpenStudy (anonymous):

and then for the y'' i got -3y-y'(-3x) --------- 4y^2

OpenStudy (anonymous):

and then I plug -3x/y on the y' right?

jimthompson5910 (jim_thompson5910):

correct and simplify

OpenStudy (anonymous):

-3y+(9x/y) ---------- 4y^2

jimthompson5910 (jim_thompson5910):

I'm not getting the same thing

OpenStudy (anonymous):

@jim_thompson5910 , from this pint do I just plug the values of x and Y?

OpenStudy (anonymous):

what did you get?
