1/3+1/8+1/10+1/15+1/21+1/28+1/36+1/45+1/55
1/3+1/8+1/10+1/15+1/21+1/28+1/36+1/45+1/55
1/3+1/8+1/10+1/15+1/21+1/28+1/36+1/45+1/55
答案,9/11-1/24
2/1 3/1 4/1 5/1 6/1 8/1 10/1 12/1 15/1 20/1
1/3+1/8+1/10+1/15+1/21+1/28+1/36+1/45+1/55
(1+1/3)*(1+1/8)*(1+1/15)*(1+1/24)*.*(1+1/9800)
1/3+1/8+1/15+1/24+.1/9800
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)快
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)=
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)怎么解?
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)
(1+1/3)(1+1/8)(1+1/15)…(1+1/99)
(1+1/3)(1+1/8)(1+1/15)…(1+1/99)
-1/3,1/8,-1/15,1/24.求通项公式
简算 1/3+1/8+1/15+.+1/120
计算1/3+1/8+1/15+...+1/120
1/3+1/8+1/15+...+1/120=?
谁会用MATLAB计算 权向量矩阵是A=[1,1/2,3,1,6,8,9,1/2 2,1,5,2,10,15,16,1 1/3,1/5,1,1/3,3,2,3,1/5 1,1/2,3,1,5,7,8,1/2 1/6,1/10,1/3,1/5,1,1,1,1/11 1/8,1/15,1/2,1/7,1,1,1,1/15 1/9,1/16,1/3,1/8,1,4/5,1,1/17 2,1,5,2,11,15,17,1];求权向量就是
((1/2)-1)*((1/3)-1)*((1/4)-1)*((1/5)-1)*((1/6)-1)*((1/7)-1)*((1/8)-1)*((1/9)-1)*((1/10)-1)
1/8+3/16 1/4-1/16 8-1分之8 6 6-60% 3/4×1/3÷5 1/2-1/5 1/2+1/10-1/5 3/5-(1/15+1/3)
(1/8+1/10)*(10.25-x)+X/15=1
