二次函数中三角形面积最大值问题解法探究

Research on the Solution of the Maximum Value of Triangle Area in the Quadratic Function

近年来,二次函数图象中以动点引起的三角形面积变化问题,因底或高的不确定性,往往不能直接利用三角形面积公式求解。此类问题综合性强,灵活多变,给学生带来了解题困扰。

In recent years,the problem of changes in the area of triangles caused by moving points in quadratic function images cannot often be solved directly using the triangle area formula due to the base or high uncertainty.This type of questions is comprehensive and flexible,and it causes problems for many students.
