三角作为高中数学重要内容,与向量、函数、方程、不等式、解几,以及平面几何等联系紧密,是高考必考内容之一,同时也颇受大学自主招生考试命题组的青睐.下面,从人教版习题出发,探讨大学自主招生三角题的复习.全日制普通高级中学教科书(必修)《数学·第一册(下)》(2006年人民教育出版社)第46页的第15,17题分别是:
As an important content of high school mathematics, triangles are closely related to vectors, functions, equations, inequalities, solutions, and plane geometry. It is one of the contents of the college entrance examination, and it is also popular among the university’s self-employment examination proposition group. Below, from Starting from the PEP exercises, we will discuss the review of university self-recruitment trigonometry. Full-time ordinary high school textbooks (required) “Mathematics First Book (Part 2)” (2006 People’s Education Press) Pages 15 and 17 The questions are:
