# Everywhere Continuous Non-differentiable Function

Weierstrass had drawn attention to the fact that there exist functions which are continuous for every value of $x$ but do not possess a derivative for any value. We now consider the celebrated function given by Weierstrass to show this fact. It will be shown that if \$ f(x)= \displaystyle{\sum_{n=0}^{\infty} } b^n \cos (a^n…
