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

解答

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

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

求解步骤

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

将

y

视为常数

使用连锁律:

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

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

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

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

化简

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

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

\frac{\partial}{\partial t} (3 t)

\frac{d v}{d t} = - 2 v - 32
