A Continuous, Nowhere Differentiable Function: Part 2 - comments

In summary, a continuous, nowhere differentiable function is a mathematical function that is continuous at every point but does not have a derivative anywhere. It is called "nowhere differentiable" because it does not have a derivative at any point. This type of function has significant implications in mathematics, particularly in the study of analysis and topology. It is possible to graph such a function, but the graph would not be a smooth curve. Part 2 of "A Continuous, Nowhere Differentiable Function" differs from Part 1 by exploring more examples and properties of these functions, as well as delving deeper into their mathematical implications and applications.

note also that the set of differentiable at least at one point functions has the first Baire category in ##C[a,b]##. This fact is much simpler to prove than to find nowhere differentiable function explicitly. So that in some sense the set of differentiable functions is very small in ##C[a,b]##
 

1. What is a continuous, nowhere differentiable function?

A continuous, nowhere differentiable function is a mathematical function that is continuous at every point but does not have a derivative anywhere. This means that the function is not smooth and has sharp turns or corners at every point.

2. Why is it called "nowhere differentiable"?

It is called "nowhere differentiable" because the function does not have a derivative at any point. This is in contrast to other functions that may have a derivative at some points but not at others.

3. What is the significance of this type of function?

This type of function has significant implications in mathematics, particularly in the study of analysis and topology. It challenges traditional notions of continuity and differentiability and has important applications in fractal geometry and dynamical systems.

4. Is it possible to graph a continuous, nowhere differentiable function?

Yes, it is possible to graph a continuous, nowhere differentiable function. However, the graph would not be a smooth curve and would have sharp turns and corners at every point. Such a graph may be difficult to visualize, but it can be represented mathematically.

5. How is Part 2 of "A Continuous, Nowhere Differentiable Function" different from Part 1?

Part 2 of "A Continuous, Nowhere Differentiable Function" explores different examples and properties of such functions, while Part 1 introduces the concept and provides a specific example. Part 2 also delves deeper into the mathematical implications and applications of continuous, nowhere differentiable functions.
