| 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
