derivative of

(x^{3} + 2 x + 6) (4 + \frac{1}{x ^{2}})

\frac{12 x ^{5} - 2 x ^{3} - 2 x - 12}{x ^{3}} + 11

Solution steps

\frac{d}{d x} ((x^{3} + 2 x + 6) (4 + \frac{1}{x ^{2}}))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{3} + 2 x + 6, g = 4 + \frac{1}{x ^{2}}

= \frac{d}{d x} (x^{3} + 2 x + 6) (4 + \frac{1}{x ^{2}}) + \frac{d}{d x} (4 + \frac{1}{x ^{2}}) (x^{3} + 2 x + 6)

\frac{d}{d x} (x^{3} + 2 x + 6) = 3 x^{2} + 2

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

= (3 x^{2} + 2) (4 + \frac{1}{x ^{2}}) + (- \frac{2}{x ^{3}}) (x^{3} + 2 x + 6)

Simplify

(3 x^{2} + 2) (4 + \frac{1}{x ^{2}}) + (- \frac{2}{x ^{3}}) (x^{3} + 2 x + 6) : \frac{12 x ^{5} - 2 x ^{3} - 2 x - 12}{x ^{3}} + 11

= \frac{12 x ^{5} - 2 x ^{3} - 2 x - 12}{x ^{3}} + 11

\int x^{2} csc (x^{3}) cot (x^{3}) d x

f (x) = - 4 x^{2} - 3 x

\frac{\partial}{\partial x} (x^{2} + y^{2} + 1)

f (x) = \frac{x}{( x - 7 ) ^{2}}

\frac{( e ^{x} + e ^{- x} )}{2}
