The concept of limits in mathematics, essential for defining values at points where functions are undefined, is rooted in the idea of closeness. John Wallis, an influential English mathematician, played a pivotal role in the development of infinitesimal calculus and formalized the modern concept of limits.
Limit, mathematical concept based on the idea of closeness, used primarily to assign values to certain functions at points where no values are defined, in such a way as to be consistent with nearby values.
