无穷级数的概念与表达式问题
首发时间:2011-12-26
摘要:无穷次加法运算无法进行;在这种意义下的无穷级数是无有意义的。必须从前n项的部分和及其序列极限意义上理解无穷级数。现有无穷级数表达式相当于约定级数和符号的意义为前n项部分和序列的极限,这种约定不恰当。应当约定级数和符号的意义为部分和序列。在这个改革意义下,无尽级数和0.9+0.09+0.009+……的意义是无穷数列0.9,0.99,0.999,……。它与1之间成立全能近似相等关系。

Questions on Concept and Expression of Infinite Series
Abstract:The operation of endless time addition could not be put into force; the infinite series have not meaning by this sense. To understand the meaning of infinite series must apply the partial sum and the limit of sequence of partial sum. The current expression of infinite series quite to appoint that sign of the infinite series is limit of sequence of partial sum. But this appointment is not suitable. This sign should be appoint the sequence of partial sum.
Keywords: Infinity Infinite series partial sum sequence of partial sum Omnipotent approximation equality
