👉 Approximative in mathematics refers to a concept that is not precise or exact, but rather is close enough to be considered reasonable or useful. It can be used to describe how well certain mathematical concepts or functions approximate their intended values. For example, in calculus, an "approximate" function (or approximation) might mean a function that has some degree of closeness to its intended value, but not exactly equal to it. In other words, the function may have a small error in its value
