limit as x approaches 0 of (sqrt(-x))/x

解答

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

不存在

求解步骤

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

不存在

x \to 0 - lim (\frac{- x}{x}) = - \infty

= 不存在

x \to 0 + lim ((4 x)^{3 x})

n \to 0 lim ((1 + \frac{1}{n})^{n})

x \to - 1 lim (2 x - x^{5})

x \to o lim (x ln (x))

x \to 2 lim (x - 1 + 3)
