limit as θ approaches pi/2 of tan(θ)

解答

θ \to \frac{π}{2} lim (tan (θ))

发散

求解步骤

θ \to \frac{π}{2} lim (tan (θ))

若

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

则极限不存在

θ \to \frac{π}{2} + lim (tan (θ)) = - \infty

θ \to \frac{π}{2} - lim (tan (θ)) = \infty

= 发散

x \to 0 lim ((1 - x)^{l n (x)})

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

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

x \to 5 lim ((x - 4) (x^{2} + 8))

x \to 5 + lim (x)
