On weierstrass's nondifferentiable function

WebThe original constructions of elliptic functions are due to Weierstrass [1] and Jacobi [2]. In these lectures, we focus on the former. Excellent pedagogical texts on the subject of elliptic functions are the classic text by Watson and Whittaker[3] … Web2 de dez. de 2009 · This is the topic in the Real Analysis class I’m teaching right now. Surprisingly, there are functions that are continuous everywhere, but differentiable nowhere! More surprisingly, it is possible to give an explicit formula for such a function. Weierstrass was the first to publish an example of such a function (1872).

Web1 Answer. Sorted by: 1. Your function is a Weierstrass function, which are of the form. W ( x) = ∑ k = 0 ∞ a k cos ( b n π x) Your function is of this form with a = 1 2 and b = 3, since then W ( x π) = f ( x).
