Is Cos X/X Uniformly Continuous. Then for each x0 2 a and for given > 0, there exists a ±(; Now, we can show that the function f(x) = 1/x2 is uniformly continuous on any set of the form [a,+∞). A function f(x) is said to be uniformly continuous on a set s, if for given ε > 0, there exists δ > 0. Let a 1⁄2 ir and f : If we can nd a which works for all x 0, we can nd one (the same one) which. I have to use the definition of uniform continuity to disprove that $\cos(\frac{\pi}{x})$ is uniformly continuous, but i don't know how to do that. It is obvious that a uniformly continuous function is continuous: Is it enough, that by heine theorem, if f(x) = cos x f (x) = cos x is continuous on x ∈ [0, 2π] x ∈ [0, 2 π], then it’s uniformly continuous on x ∈ [0, 2π]. Let us ̄rst review the notion of continuity of a function. F is uniformly continuous on [a,b]ifandonlyifforevery >0thereexists>0such that for every x,y 2 [a,b], if |y x| <then |f(y)f(x)| <. X0) > 0 such that. To do this we will have to find a δ that works for.
