20 15 The examination center of Hunan College Entrance Examination for Mathematics includes complex number calculation, determination of necessary and sufficient conditions, sampling method, basic properties of functions, trigonometric solution, images of functions, three views, plane vectors, frequency and frequency, probability of events, basic operation of sets, equations of straight lines, program block diagrams, linear programming, basic concepts and properties of hyperbola, new definition questions, evaluation of trigonometric functions, and inequality solutions. The formula for calculating the pyramid volume, the solution of the sum of the general term and the first n terms of the sequence, the standard equation of the circle, the positional relationship between the straight line and the conic curve, the properties of the exponential function, the monotonicity and monotone interval of the function, and the application of derivatives to judge the zero point of the function fully embody the propositions that the main knowledge focuses on.
Second, the examination of mathematical thinking methods
20 13 Hunan college entrance examination mathematics pays attention to the examination of mathematical thinking methods. The questions of function and equation thought are No.4, 2 1, the questions of combination of numbers and shapes are No.6, 14, 2 1, the questions of classification and integral thought are No.9 and No.22, and the questions of transformation and transformation of thought are No.5.
Third, the examination paper structure and difficulty
In 20 13, the structure of the mathematics test paper of Hunan college entrance examination remained stable as a whole, with 9 multiple-choice questions and 6 fill-in-the-blank questions. The distribution of solving problems changed from the comprehensive questions of probability, trigonometric function, solid geometry, practical application questions, analytic geometry and functional derivative inequality series last year to the comprehensive questions of trigonometric function, solid geometry, probability, series, analytic geometry and functional derivative inequality. At the same time, some of the three types of questions are sorted.
