Discussion on teaching method of sequence limit in senior high school
Summary: the limit is one of the extremely important concept in mathematics. limit mathematical solving mathematical problems in the world of thought is the awareness of the important weapons. In order to increase the speed of solving problems, solve the problem of the limit, many scholars had explored a method of calculating the limits. High school computing limits the scope of this article, discussed how the solution using contradictory characteristics, and examples to explain related methods.
