Abstract: Mathematics is an important tool for learning quantum mechanics. This paper mainly introduces the

mathematical tools that engineering students often use in the process of learning quantum mechanics，and provides

convenience for them to consult. Since this course is a basic course，this paper is mainly for the convenience of engineering

students to consult and learn quantum mechanics easier. Therefore，this article has not carried on the detailed

introduction to the mathematical knowledge involved in the book.

Key words: quantum mechanics, calculus, limit, series, function
