构造法在解某些数学问题时具有重要作用,本文通过一些典型习题,展示构造法解题的精妙之处,希望读者从中得到一些有用的启示,从而产生对数学的浓厚兴趣,增长学习数学的能力.一、构造法求值例1已知x、y、z均为正数,且x2+y2=z2,z·x2-r2=x2,求32xrzy的值.分析由条件x2+y2=z2联想勾 The construction method plays an important role in solving certain mathematics problems. This article presents some exquisite problems in the construction method through some typical exercises. It is hoped that the reader will get some useful inspirations from it, which will generate a keen interest in mathematics and increase the learning mathematics. Ability. First, the construction method evaluation Example 1 is known that x, y, z are positive, and x2 + y2 = z2, z x2-r2 = x2, find the value of 32xrzy. Analysis by the condition x2 + y2 = z2 Lenovo hook
