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

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

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

Solution steps

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

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

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

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

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

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