limit as t approaches 8 of (t(t-5)-24)/(t^2-8t)

解答

t \to 8 lim (\frac{t ( t - 5 ) - 24}{t ^{2} - 8 t})

\frac{11}{8}

十进制

1.375

求解步骤

t \to 8 lim (\frac{t ( t - 5 ) - 24}{t ^{2} - 8 t})

化简

\frac{t ( t - 5 ) - 24}{t ^{2} - 8 t} : \frac{t + 3}{t}

= t \to 8 lim (\frac{t + 3}{t})

代入值

t = 8

= \frac{8 + 3}{8}

化简

= \frac{11}{8}

z \to 2 i lim (\frac{1 - z}{1 + z})

n = 1 \sum \infty 3 r^{n}

x \to 3 - lim (2 x + 5)

x \to \infty lim (4 x + 14)

\frac{\partial}{\partial x} (54 - \frac{2}{3} x^{2} - 4 y^{2})
