derivative of x^2*y+xy^2=-2?:)

OpenStudy (anonymous):

implicit differentiation?

OpenStudy (anonymous):

u just need product rule make sure u chain the dy/dx

OpenStudy (anonymous):

yeah..lik i know how how to do it..but i dont kno wer to plug in the dy/dx...can ny1 show each step?

OpenStudy (anonymous):

whenever u take the derviative of y or y^2 u need to chain the dy/dx

OpenStudy (anonymous):

so basically..the answer is (-2x-y^2)/(x^2 +2y)?

OpenStudy (anonymous):

OpenStudy (anonymous):

so first chunk would be 2xy+(x^2)(dy/dx)+ y^2+(2y)(dy/dx)=0

OpenStudy (anonymous):

then use algebra to get dy/dx alone

OpenStudy (anonymous):

ohhok..gotcha! thanks a lot again!:)

OpenStudy (anonymous):

so move 2xy over and y^2 then devide by x^2+2y

OpenStudy (anonymous):

ohhok...thnks:)

OpenStudy (anonymous):

np :)
