2x3x4x5x6x7x8x9x10x11···x100=?
答:
100的阶乘=9.33262154 × 10^1571乘到100就是100的阶乘,数学符号是:100!具体得数是:9.332621544394415268169923885626e+157(e+157指10的157次幂),用计算器中的阶乘算最快。一个正整数的阶乘(factorial)是所有小于及等于该数的正整数的积,并且0的阶乘为1。自然数n的阶乘写作n!。1808年,基...
设级数x42?4+
x62
?4?6+x82?4?6?8+…(?∞<x<+∞)的和函数为S(x).求...
答:
(I)因为 S(x)=x42?4+
x62
?4?6+x82?4?6?8+…,所以:S(0)=0,且:S′(x)=x32+
x52
?4+x72?4?6+…=x(x22+x42?4+x62?4?6+…)=x[x22+S(x)],因此S(x)是初值问题:y′=xy+x32, y(0)=0 的解.(II) 一阶方程y′=xy+x32的通解为:y=e∫xdx[∫x32e?...
