Listen carefully in class and practice more after class.
Mathematics: Theorems in textbooks, you can try to reason on your own. This will not only improve your proof ability, but also deepen your understanding of the formula.
There are also a lot of practice questions. Basically, after each class, you have to do the questions of the after-class exercises (excluding the teacher's homework). The improvement of mathematics scores and the mastery of mathematical methods are inseparable from the good study habits of students, so good mathematics learning habits include:
Listening, reading, **, homework Listening: should grasp the main contradictions and problems in the lecture, think synchronously with the teacher's explanation as much as possible when listening to the lecture, and take notes if necessary After each class, you should think deeply about it and summarize it, so that you can get one lesson and one lesson Reading: When reading, you should carefully scrutinize, understand and understand every concept, theorem and law, and learn together with similar reference books for example problems, learn from others, increase knowledge, and develop thinking **:
To learn to think, after the problem is solved, then explore some new methods, learn to think about the problem from different angles, and even change the conditions or conclusions to find new problems, after a period of study, you should sort out your own ideas to form your own thinking rules Homework: to review first and then homework, think first and then start writing, do a class of questions to understand a large piece, homework to be serious, writing to standardize, only in this way down-to-earth, step by step, in order to learn mathematics well In short, in the process of learning mathematics, It is necessary to realize the importance of mathematics, give full play to one's subjective initiative, pay attention to small details, develop good mathematics learning habits, and then cultivate the ability to think, analyze and solve problems, and finally learn mathematics well
In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own method. Good luck with your studies!

The inductive mathematics of the knowledge points in the first year of high school is:
1. To find the monotonic interval of a function, you must first find the definition domain of the function, that is, follow the principle of "priority of the domain of function problem definition".
2. The monotonic interval must be represented by the interval, not by the set or the inequality, and the monotonic interval is generally written as the open interval, and the endpoint problem does not have to be considered.
3. It cannot be connected by "or" and "" between multiple monotonous intervals, and can only be separated by commas.
4. To judge the parity of a function, we must first consider the definition domain of the function, if the definition domain of the function is not symmetrical about the origin, then the function must be a non-odd and non-even function.
5. The image of the function is generally to simplify the analytic formula first, and then determine the image of the function by the tracing method or the image transformation method.
6. The concept of function: let a and b be non-empty sets of numbers, if according to a certain correspondence f, so that for any number x in set a, there is a uniquely definite number f(x) corresponding to it in set b, then f:a b is called a function from set a to set b denoted as:
y=f(x),x∈a.where x is called the independent variable, and the value range of x a is called the definition domain of the function; The value of y corresponding to the value of x is called the value of the function, and the set of the values of the function {f(x)|x a} is called the range of the function.
7. Mapping: In general, let a and b be two non-empty sets, if according to a certain certain correspondence law f, so that for any element x in set a, there is a uniquely determined element y corresponding to it in set b, then the corresponding f:ab is called a mapping from set a to set b.
Write as f:a b.

The knowledge points of Mathematics Compulsory 1 in Senior One are as follows:1. An infinite set of infinite elements.
2. A finite set contains a finite set of elements.
3. Image transformation includes image: translation transformation, telescopic transformation, symmetrical transformation, and folding transformation. 4. It cannot be connected by "or" and "" between multiple monotonous intervals, and can only be separated by commas.
5. If the function is formed by combining some basic functions through four operations. Well, its definition domain is the set of values of x that make each part meaningful.

The knowledge points of mathematics are summarized as follows:1. A set is a set of certain specified objects that become a set together with Qi Tong. Each of these objects is called an element. Hui Tsai Na.
2. Sets and the elements of sets are two different concepts, which are given by description in textbooks, which is similar to the concept of points and straight lines in plane geometry.
3. The set has two meanings, namely: all eligible objects are its elements; As long as it is its element, it must be symbolic conditional.
4. There are no methods before the representation of the set that are commonly used in the enumeration method, the description method and the ** method.
5. Classification of sets: finite set, infinite set, empty set.
Solution: a= x|x -5x+q=0 q 25 4x -5x+q=0 can be reduced to (x-5 2) -25 4+q=0x-5 2) =25 4-q >>>More
According to f(2)=1, we get: 2 (2a+b)=1, i.e., 2=2a+b, and because f(x)=x has a unique solution: x=ax 2+bx, i.e., ax 2+(b-1)x=0 pushes out (b-1) 2-4ac=0 >>>More
