| Abstract: | Using intermediate value theorem to calculate certain functional limits can yet be regarded as a convenient method.Nevertheless there exist problems in applications as presented in this paper.For this reason,the definition of functional limit is extended and consequently is discucsed how to me Lagrange intermediate value formula to calculate limits with examples. |
