limit as x approaches 1/4 of 8x(x-1/5)

解答

x \to \frac{1}{4} lim (8 x (x - \frac{1}{5}))

\frac{1}{10}

十进制

0.1

求解步骤

x \to \frac{1}{4} lim (8 x (x - \frac{1}{5}))

代入值

x = \frac{1}{4}

= 8 \cdot \frac{1}{4} (\frac{1}{4} - \frac{1}{5})

化简

8 \cdot \frac{1}{4} (\frac{1}{4} - \frac{1}{5}) : \frac{1}{10}

= \frac{1}{10}

x \to 0 lim (\frac{1}{1 - x})

y^{^{'}} = 0.5 (3 - y)

y^{^{''}} - 21 y^{^{'}} + 108 y = 0

\frac{d y}{d x} + 8 y = x^{2} y^{2}

\frac{\partial}{\partial x} (3 x cos (5 x y))
