Power series 幂级数(重定向自Termwise differentiation)
![]() In mathematics, a power series (in one variable) is an infinite series of the form where an represents the coefficient of the nth term and c is a constant. This series usually arises as the Taylor series of some known function. In many situations c (the center of the series) is equal to zero, for instance when considering a Maclaurin series. In such cases, the power series takes the simpler form |
