Web25 de out. de 2015 · I'm afraid there is a misunderstanding here. See the explanation section, below. I think that this question has remained unanswered because of the way it is phrased. The "continuity of a function on a closed interval" is not something that one "finds". We can give a Definition of Continuity on a Closed Interval Function f is … WebBest of all, How can you tell if a function is continuous is free to use, so there's no reason not to give it a try!

Using Weierstrass' test, from your previous estimate you see that the series is totally (hence uniformly) convergent on any bounded interval [ − a, a] . Since it is the sum of continous functions, the sum f is then continuous on every interval [ − a, a], hence on all R. (To prove the continuity of f on a given point x 0 ∈ R it ... ofripWebYou can't have a square root of a negative number, this would result in imaginary number. This is true and extends to all even roots, i.e. square root, 4th root, 6th root, so on and so on. But imaginary number only applies to even roots. You can have cube root or any odd roots of a negative number. Cube root of -1 is one example. ofrit100WebSecond question: note that $\tan(x)$ is not even continuous on $\Bbb R$, so it can't be uniformly continuous. What I mean though is that if you look at $\tan(x)$ on an open interval such as $(-\pi/2,\pi/2)$ where $\tan(x)$ is continuous but has an asymptote on the boundary, you get something that is not uniformly continuous. $\endgroup$ ofrin - make it break itWeb14 de out. de 2024 · 👉 Learn how to determine the differentiability of a function.
