Webb5 sep. 2024 · Definition 2.5.1: Limit Superior. Let {an} be a sequence. Then the limit superior of {an} \), denoted by lim supn → ∞an, is defined by. lim sup n → ∞ an = lim n → ∞ sup {ak: k ≥ n}. Note that lim supn → ∞an = limn → ∞sn, where sn is defined in (2.8). Similarly, the limit inferior of {an}, denoted by lim infn → ∞an, is ... Webb5 sep. 2024 · Example 3.2.3. We now consider. lim x → − 1x2 + 6x + 5 x + 1. Solution. Since the limit of the denominator 0 we cannot apply directly part (d) of Theorem 3.2.1. Instead, we first simplify the expression keeping in mind that in the definition of limit we never need to evaluate the expression at the limit point itself. WebbThe difference is this. Earlier, we were trying to prove a limit existed, i.e., were trying to prove a statement of the form: given ǫ > 0, some statement involving ǫ is true. To do this, you must be able to prove the truth no matter what ǫ you are given. Here on the other hand, we don’t have to prove (4)—we already deduced it from the ... fluffy fur grey pillow
