In 2022, the college entrance examination mathematics is still divided into three subjects: A, B and C, namely mathematics (literature), mathematics (science) and advanced mathematics. At present, it is impossible to determine the specific content and difficulty of the investigation, but according to the situation in previous years, the outline and the difficulty of the examination may be slightly adjusted and changed.
Students preparing for the exam should focus on the following knowledge points:
1. Functions and equations: including functions, inverse functions, composite functions, parametric equations, quadratic functions, trigonometric functions, exponential functions and logarithmic functions.
2. Analytic geometry: including the basic knowledge of vectors, analytic geometry of plane and space, calculation of three-dimensional graphics, etc.
3. Series and mathematical induction: including arithmetic progression, geometric progression, constant term series, mathematical induction, etc.
4. Trigonometric functions: including the definition, properties, operation and application of sine, cosine and tangent functions.
5. Limit and derivative: including the concept, properties, calculation and application of limit and derivative of function.
6. Probability statistics: including the basic concept of probability, the probability of events, independent events, conditional probability, expectation and variance.
Matters needing attention
1. Seriously understand and master mathematical knowledge: the system of mathematical knowledge is huge. When preparing for the exam, we should find out the relationship and internal principle of each knowledge point, pay attention to the mastery and consolidation of basic knowledge, and gradually improve the depth and breadth of each knowledge point.
2. Do more high-quality simulated test questions: High-quality simulated test questions can help candidates fully understand the test questions and difficulties, improve their test-taking ability and psychological quality, and increase their ability to cope with test variables while being familiar with the test content.
3. Pay attention to problem-solving steps and logical thinking: Good problem-solving thinking and logical reasoning ability are important factors to improve problem-solving efficiency and answer quality. When preparing for the exam, we need to pay attention to analyzing the question structure and problem-solving ideas, find out the problem-solving ideas and logical order, and be good at using logical reasoning and mathematical proof to solve difficult problems.
4. Pay attention to the improvement of mathematics application ability: Mathematics in the college entrance examination is not only theoretical knowledge and simple calculation, but also requires candidates to have mathematics application ability. When preparing for the exam, we need to pay attention to the mathematical problems based on the actual situation and improve our ability to solve practical problems by using mathematical knowledge.
5. Adjust the state properly before the exam: a lot of study and exam pressure may affect the physical and mental state of candidates, so it is necessary to pay attention to adjust the state appropriately, maintain a relaxed, confident and positive attitude, make a good time allocation and review plan, and prepare for the exam from many aspects such as adequate rest, reasonable diet and mental state.
