Mathematics in Tianjin College Entrance Examination in 2023 is still difficult. Although the content of the exam is very basic, the topic is very innovative, which brings a lot of pressure to many candidates.

The difficulty of the college entrance examination paper is related to everyone's mastery of knowledge points and the types of topics they are good at, as well as personal improvisation. The on-site status of college entrance examination candidates is very important.

Main Contents of Mathematics in College Entrance Examination

In multiple-choice questions and fill-in-the-blank questions, the contents that must be tested every year include: set, complex number, plane vector, program block diagram, linear programming, image and properties of function, image and properties of trigonometric function, evaluation of trigonometric identity transformation, three views of geometric body and its surface area or volume, equations of straight line and circle, hyperbola or parabola and their geometric properties, and counting principle (science).

Types of Required Questions in Mathematics of College Entrance Examination

First, functions and derivatives

This paper mainly examines the related concepts such as set operation, function definition domain, range, analytical formula, limit, function continuity, derivative and so on.

Secondly, plane vector and trigonometric function, trigonometric transformation and its application are the key but not difficult parts of college entrance examination, which mainly produce some basic or intermediate questions.

Thirdly, sequence and its application.

This part is the key and difficult part of the college entrance examination, which mainly produces some comprehensive questions.

Fourth, inequality.

This paper mainly investigates the solution and proof of inequality, rarely alone, mainly through the size comparison in solving problems. It is the key and difficult point of the college entrance examination.

Fifth, probability statistics.

This part is related to our life and is an applied problem.

Sixth, the qualitative and quantitative analysis of spatial position relationship is mainly to prove parallelism or verticality, and to find the angle and distance.

This paper mainly investigates the familiarity and application of the theorem.

Seventh, analytic geometry.

The college entrance examination is difficult and requires a large amount of calculation, which generally includes parameters.

The examination of the basic knowledge of mathematics in the college entrance examination is comprehensive and highlights the key points. A solid mathematical foundation is the key to successful problem solving. In view of the examination of basic knowledge and basic skills in the college entrance examination of mathematics, we must comprehensively and systematically review the basic knowledge of high school mathematics, correctly understand the basic concepts, correctly master theorems, principles, laws and formulas, and form memories and skills. Constantly changing.
