(\partial)/(\partial y)(3x^2y-y^3)

\frac{\partial}{\partial y} (3 x^{2} y - y^{3})

3 x^{2} - 3 y^{2}

Solution steps

\frac{\partial}{\partial y} (3 x^{2} y - y^{3})

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (3 x^{2} y) - \frac{\partial}{\partial y} (y^{3})

\frac{\partial}{\partial y} (3 x^{2} y) = 3 x^{2}

\frac{\partial}{\partial y} (y^{3}) = 3 y^{2}

= 3 x^{2} - 3 y^{2}
