数学高考基础知识（Basic knowledge of mathematics college entrance examination）

数学高考基础知识（Basic knowledge of mathematics college entrance examination） The basic knowledge of the mathematics of mathematics and the general conclusion I. collection and simple logic: Understanding the concepts in the collection (1) characteristics of elements in the collection: deterministic, mutual, and disordered. The intersex of the set element: for example, please; (2) the relationship between sets and elements is represented by symbols. (3) the symbol of a common number of sets: natural Numbers; Positive integer set, The integer set; Rational set, real set. (4) representation of the collection: enumeration method, descriptive method, Venn diagram. Note: to distinguish the form of elements in a collection: ; ; ; ; ; (5) empty set refers to a collection without any elements. (the difference between; 0 and the three) An empty set is a subset of any collection, a true subset of any non-empty set. Note: the conditions are not forgotten during the discussion. If, if, evaluate. Ii. Relationship between sets and operations (1) the symbol is the relationship between the element and the set, the relationship between the embodiment point and the line (surface) in the three-dimensional geometry; The symbol is the relationship between the representation and the line in the three-dimensional geometry. (2); ; (3) for any set, then: (1); ; ; (2); ; ; ; (3); ; (4) if it is even, then; If it is odd, then; If it is divided by 3, it is 0; If 3 is divided by 1, then; If you get 3 over 2, Calculation of the number of elements in the collection: (1) if there is an element in the set, the number of all different subsets of the set is _________, and the number of all true subsets is __________, and the number of all non-empty true subsets is. (2) the calculation formula of the number of elements is:; (3) application of Wayne diagram: 4. Meet the conditions, meet the conditions, If; Is a sufficient non-essential condition; If; It is the necessary insufficiency; If; The necessary and s
