limit as x approaches 0-of (11x)/(|x|)

解答

x \to 0 - lim (\frac{11 x}{∣ x ∣})

- 11

求解步骤

x \to 0 - lim (\frac{11 x}{∣ x ∣})

当

x \to 0 -

时,

x

为负. 因此

∣ x ∣ = - x

= x \to 0 - lim (\frac{11 x}{- x})

\frac{11 x}{- x} = - 11

= x \to 0 - lim (- 11)

x \to a lim c = c

= - 11

\frac{d}{d x} (100 - ln (2 x + 1))

x \to 0 lim (+ (\frac{1}{x}))

\int_{- 1}^{1} \frac{1}{x ^{\frac{4}{5}}} d x

d er i v a t i v e f (x) = (\frac{- 7}{7 x ^{2} + 1})

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