Riemann's Example of a Continuous but Nowhere Differentiable Function
Riemann's Example of a Continuous but Nowhere Differentiable Function
Contrary to intuition, functions exist that are continuous everywhere, but differentiable almost nowhere. This shows a plot of partial sums of Riemann's continuous but nowhere differentiable function which can be expressed as .
