\[3x^2-xy^3=6x\]
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
i think
OpenStudy (fanduekisses):
\[6x-y^3-3y^2*\frac{dy}{dx}*x=6\]
OpenStudy (anonymous):
lol another county heard from

hi sat 73
OpenStudy (fanduekisses):
I get \[\frac{dy}{dx}= \frac{-6-6x+y^3}{-3y*x}\]
OpenStudy (anonymous):
a medal for you
OpenStudy (anonymous):
yea just for future reference it is a lot easier to write
\[6x-y^3-3xy^2y'=6\]
OpenStudy (fanduekisses):
oh ok thanks yeah such a time saver ^_^

yeah especially here
not sure about your algebra though
OpenStudy (anonymous):
maybe just a typo
denominator should be \(-3xy^2\) you are missing the exponent on the y
OpenStudy (fanduekisses):
oops yeah hehe
OpenStudy (fanduekisses):
Thank you :)
OpenStudy (anonymous):
yw
i would also get rid of some of those minus signs, but that is just my preference, makes no difference

how?
OpenStudy (anonymous):
\[\frac{dy}{dx}= \frac{-6-6x+y^3}{-3y^2x}\]\[=\frac{6+6x-y^3}{2xy^2}\]
OpenStudy (anonymous):
but like i said, makes no difference
OpenStudy (zarkon):
the numerator looks a little off
OpenStudy (anonymous):
oops caught again

oy, the \(6\) on the right is not negative
OpenStudy (anonymous):
\[\frac{dy}{dx}= \frac{6-6x+y^3}{-3xy^2}\]
OpenStudy (anonymous):
@Zarkon always keeps me honest
OpenStudy (fanduekisses):
cool thanks :)
OpenStudy (anonymous):
now i have a question
what do you sell on ebay?
