Uniform convergence of piecewise continuous functions

Demon117 · Nov 13, 2010

I like thinking of practical examples of things that I learn in my analysis course. I have been thinking about functions fn:[0,1] --->R. What is an example of a sequence of piecewise functions fn, that converge uniformly to a function f, which is not piecewise continuous?

I've thought of letting each of these sequences of functions being piecewise in terms of the Fourier series but I am unsure this really works because I haven't figured out what it would converge to.

Any suggestions or other examples?

A sequence of continuous functions which converges uniformly has a continuous limit. I do not see how piecewise would change anything. As all sequence functions are joined at the same point, the limit will be, too.
