derivative of

\frac{1}{x ^{2} + 3}

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

Solution steps

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

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

Simplify

- \frac{1}{( x ^{2} + 3 ) ^{2}} \cdot 2 x : - \frac{2 x}{( x ^{2} + 3 ) ^{2}}

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

f (x) = - x^{3}, (- 1, 1)

\int_{- 2}^{1} 2 x d x

\frac{d y}{d x} = 5 x y

\int \frac{- 46 x + 158}{( x + 2 ) ( x - 3 ) ^{2}} d x

2 3 x
