Nettetlim n → ∞ cos a n = 1 while for another sequence lim n → ∞ cos b n = 0 In fact, as long as ℓ ∈ [ − 1, 1], we can find a sequence of points for which cos x n → ℓ. – Pedro ♦ Apr 13, 2013 at 21:01 Add a comment 6 Answers Sorted by: 9 To show that there is no such L, you can show that cos x will always assume points more than ϵ apart for some ϵ > 0. NettetFor specifying a limit argument x and point of approach a, type "x -> a". For a directional limit, use either the + or – sign, or plain English, such as "left," "above," "right" or …

Nettet20. des. 2024 · limx → ∞tan − 1(x) = π 2. limx → − ∞tan − 1(x) = − π 2. limx → ∞sec − 1(x) = limx → ∞sec − 1(x) = π 2. Example 1.8.1: Find limx → ∞sin(2tan − 1(x)). Exercise 1.8.1 Find limx → − ∞sin(2tan − 1(x)). Answer NettetMove the limit inside the trig function because cosine is continuous. cos(lim x→∞ 1 x) cos ( lim x → ∞ 1 x) Since its numerator approaches a real number while its denominator is unbounded, the fraction 1 x 1 x approaches 0 0. cos(0) cos ( 0) The exact value of cos(0) cos ( 0) is 1 1. 1 1 bullying reading
