derivative of

\frac{x ^{4}}{2}

2 x^{3}

Solution steps

\frac{d}{d x} (\frac{x ^{4}}{2})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{2} \frac{d}{d x} (x^{4})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= \frac{1}{2} \cdot 4 x^{4 - 1}

Simplify

\frac{1}{2} \cdot 4 x^{4 - 1} : 2 x^{3}

= 2 x^{3}
