The limit of a function is not always defined. In algebra, an undefined expression means a finite value does not exist, and an undefined limitis similarly defined. A limit is undefined if there is not a finite value that can be found for the limit. There are many reasons why undefined limits might exist. See more Indeterminate forms are a group of limits for which there is not a guarantee that a limit exists around x=c.
