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

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

- \frac{1}{x ^{2}}

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

= - \frac{1}{x ^{2}}

2 x^{2} y^{^{''}} + x y^{^{'}} - y = 0

y = x^{4} + 3 e^{x}, (0, 3)

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

\int_{1}^{5} x d x

\int x^{2} (ln (x))^{2} d x
