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

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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

\frac{1}{s ^{2} + 4}

7 t \cdot \frac{d y}{d t} - 4 y = t

\frac{d}{d x} (1 - sin (3 x))

\frac{e ^{- 5 s}}{s ^{2}}
