NettetIn many cases, an algebraic approach may not only provide us with additional insight into the definition, it may prove to be simpler as well. Furthermore, an algebraic approach is … NettetThe proof of L'Hôpital's rule is simple in the case where f and g are continuously differentiable at the point c and where a finite limit is found after the first round of differentiation. It is not a proof of the general L'Hôpital's rule because it is stricter in its definition, requiring both differentiability and that c be a real number.
Nettet4. mar. 2024 · It will be much easier to do this proof after going through polynomial division. In other words, we write that 3 x + 7 2 x − 1 = ( 3 / 2) ( 2 x − 1) + 17 / 2 2 x − 1 = 3 2 + 17 2 ( 2 x − 1) After that, the proof just amounts to showing that f ( x) = 17 2 ( 2 x − 1) approaches zero.

NettetAboutTranscript. The epsilon-delta definition of limits says that the limit of f (x) at x=c is L if for any ε>0 there's a δ>0 such that if the distance of x from c is less than δ, then the distance of f (x) from L is less than ε. This is a formulation of the intuitive notion that we can get as close as we want to L. Created by Sal Khan.

And such convergence has certain desirable properties. For example the limit of a linear combination of sequences is that linear combination of the separate limits; ...
