implicit ln(xy^9)=xy

implicit derivative

ln (x y^{9}) = x y

\frac{d y}{d x} = \frac{x y ^{2} - y}{x ( 9 - x y )}

Solution steps

ln (x y^{9}) = x y

Treat

y

y (x)

Differentiate both sides:

\frac{y + 9 x \frac{d y}{d x}}{x y} = y + x \frac{d y}{d x}

Isolate

\frac{d y}{d x} : \frac{d y}{d x} = \frac{x y ^{2} - y}{x ( 9 - x y )}

\frac{d y}{d x} = \frac{x y ^{2} - y}{x ( 9 - x y )}
