Continuous non differentiable functions :)

Question

I was searching for functions like Weierstrass (continuous but differentiable nowhere), but I haven't found any. If you could tell me some that would be great. Also, I would like to find some continuous functions with dense maximums.

This information would be very helpful for a research I'm doing in my university.

Thanks!

Answer 1

This looks to me as a very thorough compendium.
