- Math - Implict differentiation -
**bobpursley**, Thursday, March 25, 2010 at 5:48pmxy^2+y=2

y^2 dx + 2xy dy+dy=0

dy/dx ( 2xy+1)=y^2

dy/dx= y^2(1/(2xy+1)

dy"/dx"= 2y/(2xy+1) -y^2/(2xy+1)^2 * (2y*xdy/dx+2y)

Put for dy/dx y^2/(2xy+1)

then put number (1,-2)

CHECK MY WORK, I have a headache (Elm pollen).
