derivative of

120 + x^{3}

\frac{3 x ^{2}}{2 120 + x ^{3}}

Solution steps

\frac{d}{d x} (120 + x^{3})

Apply the chain rule:

\frac{1}{2 120 + x ^{3}} \frac{d}{d x} (120 + x^{3})

= \frac{1}{2 120 + x ^{3}} \frac{d}{d x} (120 + x^{3})

\frac{d}{d x} (120 + x^{3}) = 3 x^{2}

= \frac{1}{2 120 + x ^{3}} \cdot 3 x^{2}

Simplify

\frac{1}{2 120 + x ^{3}} \cdot 3 x^{2} : \frac{3 x ^{2}}{2 120 + x ^{3}}

= \frac{3 x ^{2}}{2 120 + x ^{3}}

\int 4 x^{- 5} + 6 x^{- 1} - 1 d x

\int (3 cos (x) + 7 sin (x)) d x

\frac{d}{d x} (sin (4 x))

\frac{\partial}{\partial u} (u)

\frac{3 y ^{2}}{4 - 15 x y}
