limit as x approaches 2/3 of (3x-2)/(3x^2-11x+6)

解答

x \to \frac{2}{3} lim (\frac{3 x - 2}{3 x ^{2} - 11 x + 6})

- \frac{3}{7}

十进制

- 0.42857 \dots

求解步骤

x \to \frac{2}{3} lim (\frac{3 x - 2}{3 x ^{2} - 11 x + 6})

化简

\frac{3 x - 2}{3 x ^{2} - 11 x + 6} : \frac{1}{x - 3}

= x \to \frac{2}{3} lim (\frac{1}{x - 3})

代入值

x = \frac{2}{3}

= \frac{1}{\frac{2}{3} - 3}

化简

\frac{1}{\frac{2}{3} - 3} : - \frac{3}{7}

= - \frac{3}{7}

\frac{\partial}{\partial z} (x y + yz + z x)

\frac{d}{d x} (x cos^{3} (x))

\int_{1}^{2} x ln (x) d x

\frac{d}{d x} (e^{(- 3 x)})
