How can you tell if a function is continuous
WebSecond 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. $\endgroup$ Web12 de jul. de 2024 · If you look at the function algebraically, it factors to this: Nothing cancels, but you can still plug in 4 to get. which is 8. Both sides of the equation are 8, so f (x) is continuous at x = 4. If any of the above situations aren't true, the function is …

Web1 de ago. de 2024 · 2 Answers. 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 ...

WebYou 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.
