椭圆是圆锥曲线中最先接触的一类,课标对其的要求是掌握方程及几何性质,椭圆的考查要求为B级,在以往的考查中,经常结合轨迹方程、直线与椭圆的位置关系等知识点综合考查,对运算能力的要求较高.椭圆的第一定义与第二定义在最值问题中是如何考查的,本文就这一点小议一下.类型一:几何最值
Ellipse conic is the first contact with a class, the standard requirements of the course is to master the equations and geometric properties, elliptical test requirements for the B level, in the past test, often combined with trajectory equation, the relationship between the line and the ellipse Such as the knowledge of a comprehensive examination, the computing power of the higher requirements of the first definition of the oval and the second definition of how to examine the value of the problem, this article on this little discussion Type one: the geometric value
