derivative of

14 x^{- 3} + x^{2} + 14

2 x - \frac{42}{x ^{4}}

Solution steps

\frac{d}{d x} (14 x^{- 3} + x^{2} + 14)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (14 x^{- 3}) + \frac{d}{d x} (x^{2}) + \frac{d}{d x} (14)

\frac{d}{d x} (14 x^{- 3}) = - \frac{42}{x ^{4}}

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

\frac{d}{d x} (14) = 0

= - \frac{42}{x ^{4}} + 2 x + 0

Simplify

= 2 x - \frac{42}{x ^{4}}

\frac{d}{d x} ((2 x + 1)^{3} (x - 3)^{4})

\int \frac{tan ( ln ( x ^{2} ) )}{4 x} d x

7 e^{t}

3 x 4 x^{2} + 4

\int x 25 + x^{2} d x
