Web8 de ago. de 2024 · Weierstrass' function is the sum of the series $$f(x) = \sum_{n=0}^\infty a^n \cos(b^n \pi x),$$ where $0 < a < 1$, $b$ is an odd natural number and $ab > 1 + 3\pi / 2$. A simpler example, based on the same idea, in which $\cos … 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). Weierstrass functions are nowhere differentiable yet continuous, and so is your f. A quote from wikipedia:
WebIn a presentation before the Berlin Academy on July 18, 1872 Karl Weierstrass shocked the mathematical community by proving this conjecture to be false. He presented a function which was continuous everywhere but differentiable nowhere. The function in question … Web2 de fev. de 2024 · Fwiw, my understanding of why this is possible is that okay, there's functions that change behaviour suddenly at a point, BUT the change in behaviour at that point is so gradual, so gentle, so smooth, that none of the function's derivatives can see the change happening; therefore, the Taylor series can't, either.
