我学习了高中选修2-1第二奄“圆锥曲线”的知识,通过对其中有关范围与最值问题不断的练习和反思,把自己的学习心得总结了一下,我认为这类问题的解决方案一般有三种:(1)利用不等式(组)求解;(2)利用函数的值域或最值求解;(3)利用(线性)规划最优解解决(数形结合)。其实就是利用数学转化化归思想把未知转化为已知的知识来解决,这也体现了数学这一学科基础为主,灵活取胜
I learned the knowledge of high school elective 2-1 second “conic curve”, summed up my learning experience through continuous practice and reflection on the range and the most value problems, I think this kind of problem There are three general solutions: (1) use inequality (group) to solve; (2) use the value of the function domain or the most value solution; (3) use the (linear) optimal solution to solve the solution (combination). In fact, the use of mathematical transformation into the thought of the unknown into known knowledge to solve, which also reflects the discipline-based mathematics, flexible win
