# Can A Discontinuous Function Be Differentiable?

## Can a discontinuous function be differentiable?

A differentiable function can have discontinuous partial derivatives. An example of such a strange function is f (x, y) = {(x2 + y2) sin (1√x2 + y2) if (x, y) ≠ (0,0) 0 if (x, y) = ( 0, 0).

## Is it possible to differentiate a discontinuous function?

We can differentiate almost any function any number of times, regardless of discontinuities. functions f, then the limit ui exists as a generalized function. Yes, this function is discontinuous at 0, but the discontinuity is direct.

## Can a function be differentiable but not continuous?

If a function is differentiable, then it is also continuous. A function can be continuous, but not differentiable. For example, the absolute value function at x = 0 is actually continuous (but not differentiable).

## Does discontinuity mean non-differentiability?

If there is a discontinuity at a certain point, then the function, by definition, is not differentiable at that point. This applies to point jumps, jumps, and infinite/asymptotic jumps. But there are also points where the function is continuous but not yet differentiable.

## Is it a different function from a retractable pause?

I conclude that the function for x = a is differentiable if the discontinuity has a solution.

## How to know if it is continuous or intermittent?

A continuous function at a point means that there is a limit of two sides at that point and it is equal to the value of the function. A separable point/space occurs when a two-sided limit exists but is not equal to the value of the function.

## Do discontinuous functions have limits?

3 answers. No, a function can be discontinuous and have a limit. The limit is simply the continuation you can do over and over again. Let f(x) = 1 for x = 0, f(x) = 0 for x ≠ 0.

## Are all continuous functions differentiable?

If bei is not continuous, then bei is not differentiable. Therefore, from the theorem above, we see that all differentiable functions are continuous. However, there are continuous functions in which they are not differentiable.

## What is the difference between continuous and differentiable?

The difference between a continuous function and a differentiable function is that a continuous function is a function where the resulting curve is a single continuous curve. This means that the curve has no breaks. A function is said to be differentiable if it has a derivative.

## Is the feature continuous in a hole?

At this point, the function is not continuous. This type of discontinuity is called a retractable discontinuity. Removable discontinuities are those where there is a gap in the graph, as in this case. … In other words, a function is continuous if there are no gaps or holes in its graph. 29

## Can a discontinuous function have a limit?

3 answers. No, a function can be discontinuous and have a limit. The limit is only one continuation that can be done continuously. Let f(x) = 1 for x = 0, f(x) = 0 for x ≠ 0.

## Can a function be continuous if it has a hole?

At this point, the function is not continuous. This type of discontinuity is called a retractable discontinuity. Removable discontinuities are those where there is a gap in the graph, as in this case. … In other words, a function is continuous if there are no gaps or holes in its graph. 29

## Is a shrinkable space a limit?

Removable imperfections are characterized by the presence of a restriction. Removable landings can be solved by redefining the function. Other types of discontinuity are characterized by the absence of a boundary.
