👉 In mathematics, "usuals" are a set of objects that satisfy certain properties. These properties include being closed under addition, multiplication, and division; being continuous (meaning it is differentiable at every point); and being uniformly continuous on their domain. For example, consider the function f(x) = x^2 - 3x + 4 defined on the interval [-1, 5]. This function satisfies all of the usuals properties because it's continuous and differentiable in its entire
