2、 归纳法及我们日常生活中常见问题等几方面的应用。依据题意建立递推关系式, 分析所建立的递推关系式的解法,学习递推关系的灵活多样的特点。如在求解数 列的通项公式时通常采用的逐差叠加法、通项代替法、递推解法等。同时让它融 入到我们的实际生活,解决我们经常遇到的一些实际实例。随着人们对递推关系 的深入和研究,形成了相当多的类型。我们对这些类型的深入研究,让递推关系 的应用更方便,使得其应用领域更为广泛。 关键字关键字:递推关系;高中数学;数列;通项公式 ABSTRACT III ABSTRACT Everything in the word we inadvertently quietly chan

The paper first Fibonacci rabbit problems introduced a simple solution to the rabbit problem Fibonacci sequen

According to the passage to establi
5、sh recursion, analysis the recursion method, learn recursion relations for the flexible characteristic. As in solving the sequence passes a formula usually differential superposition method, general substitution method, recursive solution. At the same time, make it into our real life, we often encou
6、nter some practical solutions. As the recursion relation for the development and research, has formed the quite many types. The type of in-depth research, let the applications of recurrence relation is more convenient; make its more extensive applications.
