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

解答

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

发散

求解步骤

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

若

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

则极限不存在

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

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

= 发散

\int \frac{e ^{2 x}}{( e ^{2 x} + 1 ) ^{3}} d x

\frac{d}{d x} (lo g_{5} (sin^{2} (x)))

\int 441 - x^{2} d x

x \to 0 - lim (\frac{x + 1}{x ^{2}})

\int 17 sin^{3} (x co) s^{2} x d x
