2015年北京大学优秀中学生体验营已于8月24日结束.今年的理科数学试题共5道解答题,涉及到不等式、数列、三角函数、解析几何、函数、方程等知识,突出对思维能力和解题技巧的考查.部分试题是对课内基本知识的考查,比如第3题的解析几何题;部分试题仍带有竞赛味道,对学生数学学习的深度和广度都有很高的要求.1.已知正实 2015 Peking University Outstanding Secondary Students Experience Camp ended on August 24. This year’s Science Mathematics Test has a total of 5 answers to the questions related to inequality, sequence, trigonometric functions, analytic geometry, functions, equations and other knowledge, highlighting the ability of thinking and Part of the questions is to test the basic knowledge of the class, such as the third analytic geometry problems; some questions still with the taste of competition, the depth and breadth of the students have a high degree of mathematical learning.1.
