人教A版高中数学选修4系列共有10个专题,可选学其中三个专题,分别是4-1几何证明选讲、4-4坐标系与参数方程、4-5不等式选讲。在高考中是三个专题中选做一个,到底选哪个专题的得分效率更高呢?我们从以下三个方面来看。一、三个专题介绍(1)选修4-1几何证明选讲。内容包括相似三角形的判定和性质、直线与圆的位置关系、圆锥曲线性质的探讨。考题主要以证明为主。(2)选修4-4坐标系与参数方程。内容包括坐标系、
People teach A version of high school mathematics elective 4 series of a total of 10 topics, choose one of three topics, which are 4-1 geometric proof of election, 4-4 coordinate system and parametric equations, 4-5 inequality election stresses. In the college entrance examination is one of the three topics in the election, in the end choose which topic score higher efficiency? We look at the following three aspects. One or three special presentations (1) elective 4-1 geometry proof choose to speak. The contents include the determination and properties of similar triangles, the relationship between the positions of lines and circles, and the properties of conic curves. The main test questions to prove the main. (2) Elective 4-4 coordinate system and parametric equation. Content includes coordinate system,
