WebApr 23, 2024 · 2 Answers. We begin by showing that if lim x → ∞ f ( x) = L then lim x → 0 + f ( 1 x) = L. Let ϵ > 0. Choose N > 0 such that if x > N > 0, then f ( x) − L < ϵ (here we are making use of the definition of a limit at infinity). Note that x > N > 0 is equivalent to 0 < 1 x < 1 N. Let u = 1 x and δ = 1 N. WebIn this tutorial we shall discuss an example related to the limit of a function at negative infinity, i.e. x → – ∞. Let us consider an example: lim x → – ∞ 5 x + 6 4 x 2 – 8. We divide the numerator and denominator of the fraction by x . Since we are considering only negative values of x and x 2 = x = – x for x < 0, using ...
WebDec 24, 2015 · The other limit is for changing x. As you note, lim x → ∞ ln ↑ n ( x) = ∞. for a fixed n. Those are different, since different variables are used in the limit. Of course, the double limit. lim x → ∞, n → ∞ ln ↑ n ( x) does not exist. There is nothing unusual here, since it is common for double limits to not exist, even when ...
