limit as x approaches 2 of x/(x^3-8)

解答

x \to 2 lim (\frac{x}{x ^{3} - 8})

发散

求解步骤

x \to 2 lim (\frac{x}{x ^{3} - 8})

若

x \to a^{-} lim f (x) \neq = x \to a^{+} lim f (x)

则极限不存在

x \to 2 + lim (\frac{x}{x ^{3} - 8}) = \infty

x \to 2 - lim (\frac{x}{x ^{3} - 8}) = - \infty

= 发散

x \to \frac{π ^{+}}{2} lim (tan (x))

x \to 0 lim (x^{2} \cdot csc^{2} (x))

x \to - 1 lim (ln (x^{2}))

x \to \infty lim (\frac{8 x ^{2} - 3 x}{16 x ^{2} - 1})

x \to \infty lim ([3, x])
