近年来,在中考数学压轴题中,以动点在函数图象上运动而引起三角形面积变化的问题频频出现.此类求三角形面积最大化的问题,因三角形的底与高的可变性,而不能直接利用三角形的面积公式求解,给许多考生带来解题思路的障碍而失分较多.为了更好地让考生掌握此类题型的解题思路与技巧,现将本人探究的结
In recent years, the problem of changing the area of the triangle caused by the motion of the moving point on the function image appears frequently in the finale of the upper-middle school mathematics test, and the problem of maximizing the area of the triangle is due to the bottom and the high variability of the triangle, Can not directly use the triangle area formula to solve, give many candidates obstacles to solving problems and lose more points.In order to better enable candidates to master the problem-solving ideas and skills of these types of questions, now I explore the knot
