WebAug 28, 2024 · One can define a continuous function whose curve has infinite length, even on a finite-length domain. For example, f ( x) = x cos ( 1 / x) for x ∈ ( 0, 1], and f ( 0) = 0. And there are far weirder examples of continuous functions that are impossible to draw. Consider the Cantor function or the Weierstrass function, for example.

WebContinuity of a function is an important concept in differential calculus. Questions are frequently asked in competitive exams and JEE exams from this topic. In this article, we discuss the concept of Continuity of a function, condition for continuity, and the properties of continuous function. We can say that a function is continuous, if we ... WebSep 5, 2024 · Figure 3.5: Continuous but not uniformly continuous on (0, ∞). We already know that this function is continuous at every ˉx ∈ (0, 1). We will show that f is not uniformly continuous on (0, 1). Let ε = 2 and δ > 0. Set δ0 = min {δ / 2, 1 / 4}, x = δ0, and y = 2δ0.
