所谓配凑法就是在解题过程中,对某些数学题,同时给式子的分子、分母乘以同一个不等于零的式子,或者给式子加减同一个式子,或者有目的地编造一种式子,使要解证的式子能出现某种特定的形式;或具有某种特性,使问题向特定的方向转化,最后导向问题的解决。此法是数学恒等变换中常用的方法之一,它的应用范围也较广泛。在教学中如果能不失时机地应用配凑法,它常常又是一种
The so-called patching method is the process of solving problems. For certain mathematics problems, the numerator and denominator of the formula are simultaneously multiplied by the same formula not equal to zero, or the formula is added or subtracted by the same formula, or has a purposeful To fabricate a formula so that the formula to be verified can take on a specific form; or have certain characteristics that will cause the problem to be transformed in a specific direction and finally lead to the solution of the problem. This method is one of the commonly used methods in mathematical constant transformation, and its application range is also more extensive. In the teaching, if you can use the collation method without losing the opportunity, it is often a
