哲学中,对立和统一是矛盾的两个基本属性,在某种条件下,往往又可以相互转化.在证明不等式的过程中所解决的“等”与“不等”问题也是一对矛盾,可用“增量法”将不等量变形为等量,将不等关系转化为相等关系.增量法在解题中应用较为广泛,下面以高考题和模拟题为例说明增量法在解决极值点偏移问题中的应用.一、和式增量对于实数x_2>x_1,若x_2=x_1+t,则称t为“和式增量”.在求解一类以指数型函数为背景的极值 In philosophy, opposition and reunification are two basic contradictions, and under certain conditions, they often can be transformed into each other. The problem of “equality ” and “inequality ” solved in the process of proving inequality is also a Contradictory, available “incremental method ” will not equal to the amount of deformation equivalent, the unequal relationship into equal relationship. Incremental method in solving the problem is widely used, the following test questions and simulation questions as an example Incremental method to solve the problem of extremum point offset. First, the sum of incremental For the real number x_2> x_1, if x_2 = x_1 + t, then referred to as “and incremental” The extremum of a class that is an exponential function
