Use implicit differentiation

OpenStudy (bahrom7893):

where?

OpenStudy (anonymous):

\[x^2+y=x^3+y^3\]

OpenStudy (bahrom7893):

2x+dy/dx=3x^2+3y^2(dy/dx)

OpenStudy (anonymous):

so i know that this goes to 2x+yprime=3x^2+3y^2(prime) but how do i simplify this?

OpenStudy (experimentx):

differentiate it ... seperate dy/dx ... here you have your answer

OpenStudy (anonymous):

do i divide all by yprime

OpenStudy (callisto):

2x+dy/dx=3x^2+3y^2(dy/dx) dy/dx (1-3y^2) = 3x^2 - 2x dy/dx = (3x^2 - 2x) / (1-3y^2)

OpenStudy (anonymous):

ah! i see, thanks i actually did that accept i tried to subtract it rather than divide haha

OpenStudy (callisto):

just like making dy/dx as the subject
