(\partial)/(\partial x)(sqrt(8-x^2-y^2))

\frac{\partial}{\partial x} (8 - x^{2} - y^{2})

- \frac{x}{8 - x ^{2} - y ^{2}}

Solution steps

\frac{\partial}{\partial x} (8 - x^{2} - y^{2})

Treat

y

as a constant

Apply the chain rule:

\frac{1}{2 8 - x ^{2} - y ^{2}} \frac{\partial}{\partial x} (8 - x^{2} - y^{2})

= \frac{1}{2 8 - x ^{2} - y ^{2}} \frac{\partial}{\partial x} (8 - x^{2} - y^{2})

\frac{\partial}{\partial x} (8 - x^{2} - y^{2}) = - 2 x

= \frac{1}{2 8 - x ^{2} - y ^{2}} (- 2 x)

Simplify

\frac{1}{2 8 - x ^{2} - y ^{2}} (- 2 x) : - \frac{x}{8 - x ^{2} - y ^{2}}

= - \frac{x}{8 - x ^{2} - y ^{2}}

\int \frac{1}{y ^{2} - 4} d y

\frac{d}{d x} (3 e^{- 6 x})

x \to - 2 lim (\frac{x ^{n} - 1}{x - 1})

\int \frac{5 x ^{2} + 2 x + 5}{x ^{3} - 1} d x

x \to 0 lim (8^{x})
