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

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

\frac{5}{s ^{8}}

x \to 1 lim (i n^{4} x + e^{x})

\int_{0}^{\frac{π}{6}} sin^{4} (6 x) d x

\int \frac{( x + 4 )}{x ^{3} + 3 x ^{2} - 10 x} d x

\frac{d}{d x} (- 6 x^{2})
