*Note:- 1) If y = x^n ; then dy/dx = n*x^(n-1) ; where 'n' = real number *

*2) If y = u*v ; where both u & v are functions of 'x' ; then*

*dy/dx = u*(dv/dx) + v*(du/dx)*

*3) If y = k ; where 'k' = constant ; then dy/dx = 0*

*Now, the given function is :-*

*2*(x^3) + (x^2)*y - x*(y^3) = 2*

*differentiating w.r.t 'x' on both sides we get,*

*6*(x^2) + 2xy + (x^2)*(dy/dx) - (y^3) - 3x*(y^2)*(dy/dx) = 0*

*or, [6(x^2) + 2xy - (y^3)] = [3x*(y^2) - (x^2)]*(dy/dx)*

*or, dy/dx = [6(x^2) + 2xy - (y^3)]/[3x*(y^2) - (x^2)]*
