derivative of sqrt(6+7x)

解答

\frac{d}{d x} (6 + 7 x)

\frac{7}{2 6 + 7 x}

求解步骤

\frac{d}{d x} (6 + 7 x)

使用连锁律:

\frac{1}{2 6 + 7 x} \frac{d}{d x} (6 + 7 x)

= \frac{1}{2 6 + 7 x} \frac{d}{d x} (6 + 7 x)

\frac{d}{d x} (6 + 7 x) = 7

= \frac{1}{2 6 + 7 x} \cdot 7

化简

\frac{1}{2 6 + 7 x} \cdot 7 : \frac{7}{2 6 + 7 x}

= \frac{7}{2 6 + 7 x}

t a y l or e^{3 x}, 0

\int x^{2} (5 x^{2} + x)^{2} d x

\frac{\partial}{\partial h} (\frac{1}{2} (a + b) h)

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

y^{^{''}} - 2 y^{^{'}} + 5 y = 5, y (0) = 2, y^{^{'}} (0) = 1
