2013年高考第二轮复习数学全国文科第3讲 解答题题型特点与技法指导(国外英语资料) Third questions to explain the characteristics and techniques of the instructions of college entrance examination questions generally have six directions: trigonometric function and plane vector, probability and statistics, geometry, sequence and analytic geometry, inequality, inequality and function and derivative. In general, the first three questions belong to the middle and low grade, fourth is a mid-range partial problem, after two is a question problem. The high probability appeared trigonometric and plane vector probability and statistics, three-dimensional geometry in the first three questions, grasp the method of solution of these problems is the key to the success of most students. The college entrance examination questions, the current has been transformed by the comprehensive knowledge alone is comprehensive knowledge, method and ability to answer can do the problem. To answer questions is the key to the.1. triangle function, the success of college entrance examination The big question about trigonometric function solutions of the answer, is mainly the basic knowledge, basic skills and basic research methods, and is not difficult. Highlight the identity transform and trigonometric function image, examine properties within the triangle. Mainly focus on the following 4 aspects: image, character, image transformation of triangle function, mainly y (= Asin Omega phi X) image, character and image transform B, trigonometric functions, the concept of parity, periodicity, monotonicity, and the value of image translation and symmetry; the triangle identical transformation, flexible use, mainly examines the formula change ability, generally need to use double angle formula, and the angular difference the formula, especially the comprehensive application and properties of trigonometric function formula; the application of trigonometric functions, by solving triangle triangle identical deformation and to examine the nature
