语法

SERIESSUM (x, n, m, coefficients)

争论

Argument	描述	Required/Optional
X	The input value to the power series.	Required
N	The initial power to which you want to raise x.	Required
M	The step by which to increase n for each term in the series.	Required
Coefficients	A set of coefficients by which each successive power of x is multiplied. The number of values in coefficients determines the number of terms in the power series.	Required

Notes

• 幂级数的总和为

  $SERIESSUM(x,n,m,a)= a_1x ^ n + a_2x ^ {(n + m)} + a_3x ^ {{n + 2m)} + ... + a_jx ^ {(n +(j -1)m)} $

  其中(a ₁ ,a ₂ ,a ₃ …a _j )是系数集

• 如果任何指定的参数都是非数字的,则SERIESSUM返回#VALUE!错误
