limit as x approaches-0 of xln(x)

解答

x \to - 0 lim (x ln (x))

不存在

求解步骤

x \to - 0 lim (x ln (x))

若

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

则极限不存在

x \to - 0 + lim (x ln (x)) =

未定义

x \to - 0 - lim (x ln (x)) =

不存在

= 不存在

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

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

x \to 3 lim (x^{3} - 3 x^{2} + 3 x - 1)

x \to 2 - lim (\frac{x}{4 - x ^{2}})

x \to \infty lim (- cot (x))
