derivative of x=(y^3)/(3+y)

derivative of

x = \frac{y ^{3}}{3 + y}

\frac{d y}{d x} = \frac{9 + 6 y + y ^{2}}{y ^{2} ( 9 + 2 y )}

Solution steps

x = \frac{y ^{3}}{3 + y}

Treat

y

y (x)

Differentiate both sides:

1 = \frac{9 y ^{2} \frac{d y}{d x} + 2 \frac{d y}{d x} y ^{3}}{( 3 + y ) ^{2}}

Isolate

\frac{d y}{d x} : \frac{d y}{d x} = \frac{9 + 6 y + y ^{2}}{y ^{2} ( 9 + 2 y )}

\frac{d y}{d x} = \frac{9 + 6 y + y ^{2}}{y ^{2} ( 9 + 2 y )}
