limit as x approaches infinity of 11x

解答

x \to \infty lim (11 x)

\infty

求解步骤

x \to \infty lim (11 x)

运用无穷大属性:

x \to \infty lim (a x^{n} + \dots + b x + c) = \infty, a > 0,

n is odd

a = 11, n = 1

= \infty

x \to 3 - lim (ln ∣ x - 3 ∣)

t \to π lim (sin (\frac{4}{3} t))

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

x \to 0 lim (x^{2} - 7 x + 10)

x \to 0 lim (\frac{ln ( ln ( x ) )}{x})
