Abstract: As a tool of analytic function,Taylor series has both theoretical and practical significance in solving complex function theory.By summarizing and analyzing several methods of expanding Taylor series,combining with the application examples of Taylor series in higher derivative,approximation,integral and limit,this paper proves the calculation skills and advantages of Taylor series in these aspects,and explains that Taylor series plays an important role in solving various mathematical problems.

Keywords: Taylor series;Analytical function;Higher-order derivative
