Zero Points and Their Distributions of Real and Complex Functions

Abstract

<jats:p>The zero point of function is an important feature of function, and it is an important medium for communication between function and equation. This paper analyzes and summarizes the existence, number and distribution of zero points of real and complex functions, and illustrates them with examples, aiming at deepening readers' understanding of zero points of functions and playing a certain reference role for teachers' teaching and students' learning.</jats:p>
