The trouble you interpret this cough up!!!!!!!!!!! Don't online!Series summation is one of the basic contents of sequence, but also the main entrance. In recent years, the college entrance examination in the volume of the summation series, pay more attention to examine innovation ability, which requires us to the summation series for different questions master certain methods and techniques. But for these students of processing method commonly used is mathematical induction and general inequality halfway, often do without. The author inspired by sequence and form of the inequalities proved not only examines the summation methods flexibly, also examines the proof of the techniques in. Using a recursive formula for the general term of the general analysis to sequence and, this is the students have mastered the method, In general, reasonably as the summation series to prove, this paper attempts to explore the inequality is the problem. Based on the analysis of several examples are effective solution, make the students in this class problem solution, can communicate and flexible use of knowledge, clever sequence to the proper sequence of general purpose is that the "towards the" these "target", making it easy and rapid solutions in peace.
