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

解答

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

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

求解步骤

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

将

y

视为常数

使用连锁律:

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

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

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

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

化简

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

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

x \to 0 + lim ((1 + x)^{(\frac{1}{x})})

\frac{d}{d x} (25 x^{3} - 6 x^{2} + 7 x - 88)

\frac{d y}{d x} = 0.1 y (1 - \frac{y}{500})

9 y^{^{''}} - 24 y^{^{'}} + 16 y = 0

d er i v a t i v e y = \frac{1}{( x ^{2} - 2 ) ( x ^{2} + x + 5 )}
