Mathematical formula that must be memorized in college entrance examination:

Formula of circle: including volume, area and perimeter of circle, standard equation and general equation of circle, etc. Ellipse formula: ellipse circumference formula, ellipse circumference theorem, ellipse area formula, etc. Two-angle sum formula: including sine, cosine, tangent two-angle sum formula and half-angle formula.

Double angle formula: including sine, cosine and tangent double angle formula. Sum-difference product of trigonometric function and sum-difference formula of product. Arithmetic progression and geometric progression's general formula and summation formula, etc. Parabola and other formulas.

Key points of college entrance examination mathematics:

1, function and derivative: function is the basis of high school mathematics, and derivative is an important tool for function research. Students need to understand the properties and images of functions, master the methods and applications of derivative, and understand the application of derivative in studying monotonicity and extremum of functions.

2. Trigonometric function: Trigonometric function is one of the important contents of high school mathematics, including the images and properties of sine, cosine, tangent and other functions, as well as trigonometric identity transformation and trigonometric equation. This part requires students to master the periodicity, symmetry and maximum value of trigonometric functions, and to be able to simplify and evaluate them by using trigonometric identity transformation.

Math learning methods of college entrance examination:

1, make a study plan:

Before you start your study, make a clear and executable study plan. This plan should include daily study tasks, weekly study goals and monthly study plans. In this way, you can arrange your study time in an orderly way and avoid wasting time and energy.

2, pay attention to the basic knowledge:

Mathematics is a subject that needs a solid foundation. In the process of learning, we should pay attention to learning and mastering basic knowledge, such as algebra, geometry, probability and so on. Only by mastering these basic knowledge can we better understand and apply more complex concepts and skills.

3. Do more exercises:

Mathematics is a subject that needs a lot of practice to improve skills. By doing more exercises, you can better grasp the knowledge points, understand the characteristics and solutions of various questions, and improve the speed and accuracy of solving problems.

4, establish the wrong book:

In the process of learning, it is inevitable to encounter the problem of doing something wrong. Setting the wrong questions is a very good learning method. Record the wrong questions, analyze the reasons and correct them. This can prevent the same mistakes from happening again and improve learning efficiency.
