数列、数学归纳法及数列极限的复习一、基本概念1 数列：按一定次序排列的一列数.按项数是否有穷可分为有穷数列和无穷数列.按相邻两项的大小关系可分为递增数列、递减数列、常数数列和摆动数列.数列可以看成一类特殊的函数，其定义域为正整数集或其子集.数列na的第n项na与n的关系式)(nfan叫做数列na的通项公式.注意：不是每个数列都有通项公式！根据数列的前几项不能确定这个数列，但是可以写出它的一个或几个通项公式！有些数列有单调性、周期性、最值.2 数列的递推公式：给出数列na的初始项(第一项或前几项)，再给出相邻两项或几项的关系，这样的关系式称为数列na的递推公式.如：daaaann 101，nnqaaaa101，nnnaaaaa12211,1等.3 等差数列若daann 1(d为常数)，则数列na是等差数列.公差为d的等差数列na的通项公式为dnaan)1(1.(该公式可整理为)(1dadnan)设na是等差数列，若),(2都是正整数ktsqpktsqp，则kqpnmaaaaa2.注意：nmnmaaa一般不成立！设na是等差数列，则na的前n项和nS的公式为dnnnaaanSnn2)1(2)(11.(该公式可整理为ndandSn)2(212).若等差数列na的公差0d，则na是递增数列.若0d，则na是常数数列.若0d，则na是递减数列.若bAa,成等差数列，则2baA.任意两个实数都有唯一的等差中项.判断na是等差数列的方法：(1)利用定义daann 1(d为常数).(2)根据nnnnaaaa112.(3)根据qpnan.(4)根据bnanSn2.注意：证明数列na是等差数列时通常用定义！4 等比数列若qaann 1(q为常数)，则数列na是等比数列.公比为q的等比数列na的通项公式为mnmnnqaqaa11.设na是等比数列，若),(2都是正整数ktsqpktsqp，则2kqpnmaaaaa.设na是等比数列，则na的前n项和nS的公式为)1(1)1(1)1(111qqqaqqaaqnaSnnn.等比数列na的公比0q.若bGa,成等比数列，则abG.两个实数不一定有等比中项，若有等比中项，则有两个！判断na是等比数列的方法：(1)利用定义qaann 1(q为常数).(2)根据nnnnaaaa112.(3)根据nnbqa.(4)根据bbqSnn.注意：证明数列na是等比数列时通常用定义！5 数学归纳法对于关于正整数n的很多命题可以用数学归纳法解决.它是用有限的步骤完成无限的递推！第一步，证明0nn时命题成立(这是递推的基础).第二步，假设),(0nkNkkn命题成立.由此证明1kn时命题也成立(这是递推的依据).根据这两步，就可以无限递推下去，因而对于任意的正整数0nn，命题都成立.数学归纳法的第二步必须用假设的结论！6 数列的极限几个基本数列的极限：)(01limNmnmn.当1x时，0limnnx.CCnlim(C为常数).运算法则：若BbAannnnlim,lim，则(1)BAbabannnnnnnlimlim)(lim.(2)BAbabannnnnnnlimlim)(lim.文档编码:CG3O6K1D2X7 HQ8B6S4P4B7 ZD4M9N10L1J10文档编码:CG3O6K1D2X7
