纵观近几年高考数学卷,很多压轴试题多为数列与不等式相交汇的试题,其中往往涉及证明数列型不等式.这类问题融计算、推理于一体,不但考查证明数列不等式的各种方法,也是对考生的数学阅读、理解、转化等能力的综合考量,难度不小.碰到这样的问题,考生第一时间往往会望而生畏,真可谓:“想说爱你不容易”.其实数列型不等式的求解或求证是万变不离其宗的,只要解题策略正确、方法得当,还是有章可循的.因此,
Throughout the recent years college entrance examination mathematics volume, many of the finale questions mostly for the series and inequality intersection problems, which often involve the proof of series inequality.This kind of problem financial calculation, reasoning in one, not only examining the numerical inequality of the various methods, Is also a comprehensive consideration of the examinee’s math reading, understanding, transformation and other capabilities, the difficulty is not small.Ever such a problem, the candidate is often the first time daunting, indeed: “want to say that love is not easy ” .In fact, the number of The inequality of solving or proving is invariant, as long as the problem-solving strategy is correct, the method is proper, there is a rule to follow.Therefore,
