数列解答题在近五年全国新课标卷的难度有所降低,往往和三角函数解答题交替考查.基本格局是:如果有数列大题,则可能没有数列小题;如果有三角函数大题,则可能会有两个数列小题.“一大或两小”的命题格局趋于稳定,常见的类型有:(1)是对数列的概念、等差或等比数列的定义与性质、数列求和、数列的综合应用等 The number of answer questions in the past five years, the difficulty of the new national standard volume test is reduced, and often alternating trigonometric function test questions. The basic pattern is: If you have a series of questions, you may not have a series of questions; if you have a trigonometric function , There may be two series of small problems. “One or two small ” proposition pattern tends to be stable, the common types are: (1) is the concept of logarithm, Nature, summation of series, the comprehensive application of series
