limits - What is an essential discontinuity? Is it infinity or non ...
An infinite discontinuity occurs whenever a one-sided limit is $\pm \infty$. Thus, an infinite discontinuity is a type of essential discontinuity. More specifically: If both the right- and the left-hand limits are equal to $\pm \infty$, then the infinite …
real analysis - What type of discontinuity is $\sin (1/x ...
So it isn't a removable discontinuity. One might call this an essential discontinuity. As defined in the Wikipedia article, one might also call this an infinite discontinuity (but in my opinion one should keep that term for then one of the sided limits is plus or minus infinity).

1. Sketch a graph of a function f that satisfies each of the following. (Feel free to use the circles to check off each. condition as you graph it, or you can check them off to double check your graph.) Ofis continuous everywhere except at four points, x = -8, x=-3, x = 0 and x = 6. O fhas an oscillating discontinuity at x = 0. O fhas a removable
calculus - Can a function be differentiable on an interval, but not ...
This function is diffrentiable everywhere and continuously differentiable everywhere except 0, where the derivative has an oscillating discontinuity. It seems like if a function is differentiable on an interval containing the discontinuity in the derivative, you couldn’t get the derivative to be discontinuous any other way besides an ...
Determine the discontinuities of the following function
2018年6月5日 · For each discontinuity identified above, classify whether the discontinuity are removable, jump discontinuity, infinite or oscillating. Answer: From the definition of the function, we see that; The functions $ \ f(x) \ $ has discontinuities at $ \ x=0, \ x=1, \ x=2 \ $ Among this, $ x=2 \ $ is removable singularity, jump discontinuity.
