Abstract

As the name implies, the real variable function is a function with real numbers as independent variables. In the process of solving problems in the real problem, using forward reasoning, the use of forward reasoning often cannot solve more complicated mathematical questions. Therefore, timely adoption is reversed. The applied method not only provides a thorough understanding of mathematical theory and concepts, but also provides a variety of problem-solving ideas for solving similar types of questions.
