Teaching Infrospection of Many Testimonies on an Important Limitation
HU Qi-ming · College Mathematics · 2011
In the teaching of mathematical analysis,number sequence limitation—lim n→∞n/an=0(a1)—has once been testified to in e-N language.However,it should be generalised to number sequence limitation—lim n→∞nk/an=0(a1,k∈N) in more calculations or testimonies.How to elicitate upper students to testify to the generalised limitation remains important and difficult in classroom teaching.
