limit as x approaches 3 of 2/((x-3)^3)

解答

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

发散

求解步骤

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

若

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

则极限不存在

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

x \to 3 - lim (\frac{2}{( x - 3 ) ^{3}}) = - \infty

= 发散

\int \frac{1}{x ^{2} 5 x ^{2}} d x

x \to 1 lim (\frac{17 - x ^{2} - 4}{x - 1})
