(\partial)/(\partial x)(1/(sqrt(x^2+a^2)))

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

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

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

\frac{7}{s ^{2} + 5 s + 10}

(20 + x^{2}) y^{^{'}} - 2 x y = 0

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

(4 x - 3)^{4}
