derivative sqrt(y/4)

解答

导数

\frac{y}{4}

\frac{1}{4 y}

求解步骤

\frac{d}{d y} (\frac{y}{4})

使用连锁律:

\frac{1}{2 \frac{y}{4}} \frac{d}{d y} (\frac{y}{4})

= \frac{1}{2 \frac{y}{4}} \frac{d}{d y} (\frac{y}{4})

\frac{d}{d y} (\frac{y}{4}) = \frac{1}{4}

= \frac{1}{2 \frac{y}{4}} \cdot \frac{1}{4}

化简

\frac{1}{2 \frac{y}{4}} \cdot \frac{1}{4} : \frac{1}{4 y}

= \frac{1}{4 y}

\frac{\partial}{\partial x} ((x - \frac{a}{y ^{3}}) (b - x))

\frac{d P}{d t} = 7 Pt, P (1) = 5

n = 1 \sum \infty \frac{1}{n} (- 1)^{n}

- y^{^{''}} + 3 y^{^{'}} = 0
