(\partial}{\partial x}(\frac{x^3)/3+4y)

\frac{\partial}{\partial x} (\frac{x ^{3}}{3} + 4 y)

x^{2}

Solution steps

\frac{\partial}{\partial x} (\frac{x ^{3}}{3} + 4 y)

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

= \frac{\partial}{\partial x} (\frac{x ^{3}}{3}) + \frac{\partial}{\partial x} (4 y)

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

\frac{\partial}{\partial x} (4 y) = 0

= x^{2} + 0

Simplify

= x^{2}
