Application of Definite Integral Definition to the Proof and Solution to Limit
Ligang Geng · Journal of Chongqing Technology and Business University · 2013
The value of definite integral is only related to integral function and integral interval but is not related to the method of interval division and the method for choosing point ξi.The definition of definite integral can be used to choose reasonable interval division method and point ξiselection method,which can not only simplify the proofs related to definite integral but also be able to deal with some complex problems in the solution to limit.
