14 de abr. de 2016 · 7. "$\ldots = DNE$" is not standard mathematical terminology. Obviously the intention is simply to say that the thing in question does not exist. – Robert Israel. CommentedApr 14, 2016 at 22:44. 1. You could define a non-existent limit as being equal to "DNE", just as long as you realize that DNE is not a real number.
5 de fev. de 2022 · If $ 0 \cdot DNE$ can be equal to zero, then why is $ 0 \cdot \infty$ indeterminate? I understand that infinity is not a number but a concept and there's no way to determine $ 0 \cdot \infty$ to be anything else. But why is DNE a special case if it is not a number too? Thanks!

The question asks to show that the limit DNE. According to the rule you mentioned, it means that the denominator will reach 0 0 faster than numerator, so that the equation DNE as (x, y) → (0, 0) (x, y) → (0, 0)? – user95087. Oct 6, 2013 at 16:19. 1. It is not an equation at all, it is a limit which doesn't exist.
1. This is only a matter of definition, nothing is more correct. There is a proper definition for limits being ±∞ ± ∞, just write whatever the problems asks of you. On a side note: I don't think " = DNE" is standard notation at all. – Stefan Perko. Feb 12, 2015 at 19:31. 2. The formula lim x→10− ln(100 −x2) = −∞ lim x → 10 ...
21 de set. de 2020 · However, both limits DNE. And I need to come up with possible examples for each function so that the limit of the sum of the two produces a given number. So, my question is, can the limit of the sum of the functions still exist even if individually, the limits of each function DNE? If anyone could help out, that'd be great. Thanks
23 de dez. de 2018 · 2. According to Math - Symbol for Undefined, dividing a number by 0 0 may be represented by UNDEF, but the staff are unaware of any specific symbol meaning "undefined". For what it's worth, I also am unaware of any such symbol, at least anything which is generally accepted by the math community. – John Omielan.
8. $\begingroup$. It is easy to prove the limit exists, all we have to show is there exists a relationship between $\delta$ and $\epsilon$. But how are we supposed to prove limit doesn't exists? The problem is when we are proving for a limit we already know what the limit is and with that, algebra is all that's needed.
