1, a mathematical function covers all aspects of functions, including elementary functions, trigonometric functions, exponential functions and so on. Compared with a mathematical function, the content of Xue Kui's mathematical motif is not comprehensive enough, and some complicated concepts and problems are not clearly explained.

2. A mathematical function gives a detailed proof and explanation of every concept and problem, which is helpful for students to understand. Because this book pays more attention to the cultivation of mathematical thinking, some concepts and problems will be more complicated and abstract for beginners.
