👉 The term "undulative" refers to a set of numbers that cannot be put into a finite number system, such as the real or complex numbers. It is often used in mathematics and other fields where a limit does not exist, meaning that there is no value to which an infinite sum approaches. For example, in calculus, if we consider limits at infinity, it's clear that the limit of 1/(x^2 + x) as x approaches 0 cannot be approached by any finite
