limit as x approaches 0 of-4x^{-3}

解答

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

发散

求解步骤

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

若

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

则极限不存在

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

x \to 0 - lim (- 4 x^{- 3}) = \infty

= 发散

\frac{\partial}{\partial y} (x y^{2} e^{x^{2}})

x \to - 1 - lim (2 x^{2} - 4 x + 8)

\frac{\partial}{\partial x} (6 x y + 5 yz + x z - 48)

16 y^{^{''}} + 152 y^{^{'}} + 361 y = 0, y (0) = 9, y^{^{'}} (0) = 2

\frac{\partial}{\partial y} (ln (1 + x^{2} + y))
