Abstract:

  In this paper, some limit problems in higher mathematics using fitting method were studied. Specific steps are as follows: first of all, the target limit value is decomposed according to the known conditions. Secondly, based on the target limit and proper fitting method, the limit problem is transformed into functional fitting problem. The function fitting reduces the difficulty of the problem and finds a break through to resolve the limit problems. Numerical examples demonstrate that the proposed fitting based approach for limit problems not only can simplify complex issues but also provides views for some problems which seem can't solve. This method has an advantage of wide range of application.

Key words: fitting, prove, limit
