Stick to the outline and highlight the core.

The examination papers of mathematics, arts and sciences are based on the questions of function and derivative, solid geometry, analytic geometry, probability statistics, trigonometric function and series, which constitute the main framework of senior high school mathematics, with 22 points each, * * * accounting for 1 10. Recursive formula and summation of the relationship between arithmetic progression and sum term in series investigation: the triangular problem-solving type is characterized by solving two types of triangle questions, plus two multiple-choice questions of trigonometric identity transformation and image properties; This paper discusses the geometric calculation of three views and space, the calculation of parallel angle and vertical angle, the calculation of volume and surface area, and solves the synthesis problem of three kinds of conic curves and straight lines. Function examines zero, image, derivative, monotonicity, maximum, or finale.

Based on reality, pay attention to application

Proposition emphasizes the application of mathematics, which not only examines the application of mathematical knowledge and methods in disciplines, but also examines the application of mathematical knowledge in solving practical problems. For example, the second question of liberal arts solves the comparative analysis and evaluation of crop yield, and the question of liberal arts 19 examines the problems of product quality supervision and sampling analysis and investigation in real life, which embodies the inseparable connection between mathematics and real life.

Basic and routine inspection

The proposition covers nearly 80% of the basic questions, which is not difficult, but requires students to master the textbook knowledge in an all-round way. Wen and Li 23 studied the transformation of polar coordinates, parametric equations and ordinary rectangular coordinate equations, and the triangle substitution for solving the maximum distance in curve parametric equations. The thinking of solving problems is clear, the amount of calculation is average, and the overall difficulty is not great. The basis of the question type, the question directly hits the test center, concise and to the point. To make candidates feel more intimate, from the form of test questions, analysis ideas to problem-solving methods, students often train routine questions in daily training. For students with a solid foundation, it is easy to examine the questions.

Moderate innovation, selective ability

The proposition pursues stability and innovation, and moderately examines the ability to transfer existing knowledge and methods to new situations to solve problems. Li Ru 12 comprehensively examines the reasoning and argumentation ability, operational solving ability and innovative consciousness based on the number series; Text 4 and Science 2 all take "Taiji Eight Diagrams" as the proposition carrier, investigate the calculation of probability, and pay attention to the propaganda and understanding of China traditional culture; Wen 6, 16, Li 7, 16 comprehensively investigated students' spatial thinking ability with three views and balls as carriers.
