圆锥曲线是解析几何的重点内容,这部分内容的特点是综合性强。在解题中几乎处处涉及函数与方程、不等式、三角及直线等内容,体现了对各种能力的综合要求。计算量大,要求学生有较高的计算水平和较强的计算能力,而很多学生由于基础知识掌握欠缺,运算能力差,综合能力弱,因此这部分试题是错误高发区。下面举例说明,以此为戒。1.忽略前提条件 Conic curve is the focus of analytic geometry, the content of this part is characterized by comprehensive. Almost everywhere in the problem-solving functions and equations, inequalities, trigonometry and straight lines, etc., reflects the comprehensive ability of a variety of requirements. The calculation is large, requiring students to have a higher level of computing and computing power, and many students because of lack of basic knowledge, poor computing power, comprehensive ability is weak, so this part of the test is the high incidence of errors. Here’s an example, as a warning. 1. Ignore the preconditions
