圆锥曲线在解析几何中占有非常重要地位,在高考中每年也是必考的内容,椭圆是圆锥曲线中接触的第一种曲线,要学好这一章,学好椭圆起着至关重要的作用.而椭圆中的最值问题是比较重要的课题,它主要体现了转化思想及数形结合的应用,涉及到的知识有椭圆定义、标准方程、参数方程、三角函数、函数等内容,下面介绍几种常见的与椭圆有关的最值问题的解决方法. Conic in analytic geometry occupies a very important position in the college entrance examination is also necessary to test the content, the oval is the conical curve of contact in the first kind of curve, to learn this chapter, learning oval plays a vital role. The most value problem in the ellipse is a more important issue. It mainly embodies the application of the transformation idea and the combination of several forms. The knowledge involved includes the definition of ellipses, standard equations, parametric equations, trigonometric functions, functions, etc. The following describes several Common ellipse-related solutions to the most value problems.
