limit as x approaches-6 of (x^2+8)/(x+6)

解答

x \to - 6 lim (\frac{x ^{2} + 8}{x + 6})

发散

求解步骤

x \to - 6 lim (\frac{x ^{2} + 8}{x + 6})

若

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

则极限不存在

x \to - 6 + lim (\frac{x ^{2} + 8}{x + 6}) = \infty

x \to - 6 - lim (\frac{x ^{2} + 8}{x + 6}) = - \infty

= 发散

\frac{d}{d x} (\frac{cos ( ln ( x ) )}{x})

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

\int - 75 x^{2} + 600 x + C d x

\int x^{2} 3 + x^{3} d x

(x^{2} + y) d x + (x + e^{y}) d y = 0
