[SOLVED] Implicit Differentiation
-4x^2+3xy+4y^3=-328
This is at the point (3,-4)
and i am trying to find m
here is my work
-4x^2+3xy+4y^3=-328
-8x+3xy'+3y+12y^2y'=0
-8x+3y=-3xy'-12y^2y'
-8x+3y=[-3x-12y^2]y'
y'=(-8x+3y)/(-3x-12y^2)
plug in x=1,y=3 then solve and get
m=-12/67
can you find the error?
It would be very much appreciated
thank you.
