Many concepts in mathematics are closely related, such as parallel line segment and parallel vector, plane angle and space angle, equation and inequality, mapping and function, opposite event and mutually exclusive events. In teaching, we should be good at discovering and analyzing their connections and differences, which will help students grasp the essence of concepts. For another example, the concept of function has two definitions. One is the definition given by junior high school, which is from the point of view of motion change, and the corresponding relationship is to correspond each value of independent variables with a unique function value; The other is the definition given by high school, which is based on the viewpoint of set and correspondence, in which the correspondence is to correspond each element in the original image set with the only determined element in the image set.
