derivative of

\frac{1}{s ^{2} + 1}

- \frac{2 s}{( s ^{2} + 1 ) ^{2}}

Solution steps

\frac{d}{d s} (\frac{1}{s ^{2} + 1})

Apply exponent rule:

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

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

Apply the chain rule:

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

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

\frac{d}{d s} (s^{2} + 1) = 2 s

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

Simplify

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

= - \frac{2 s}{( s ^{2} + 1 ) ^{2}}

\frac{1}{3} cot (9 x)

x \to - 2 - lim (f (x))

\frac{d}{d x} ((2 x^{2} - 9)^{- 1})

\frac{d}{d x} (3 x^{2} - 5 x + 2)

\frac{4}{t ^{2}} - \frac{2}{t}
