(1-1/2-1/3-1/4-……-1/2003)(1/2+1/3+1/4+...+1/2004)-(1-1/2-1/3
(1-1/2-1/3-1/4-……-1/2003)(1/2+1/3+1/4+...+1/2004)-(1-1/2-1/3
计算【1/3-1/2】+【1/4-1/3】+【1/5-1/4】+……+【1/2004-1/2003】
(1-1/2)(1/3-1)(1-1/4)(1/5-1)……(1/2003-1)(1-1/2004)
数学题解答|1/3-1/2|+|1/4-1/3|+|1/5-1/4|+…+|1/2004-1/2003|
1.(1/2+1/3+…+1/2003)(1+1/2+1/3+…+1/2004)-(1+1/2+1/3+…+1/2003
1\2004+2/2004+3/2004+4\2004+5\2004+……+2002\2004+2003\2004
1/(1-1/2)/(1-1/3)/(1-1/4)/……/(1-1/2012)
计算:(1/2006-1)(1/2005-1)(1/2004)… (1/3-1)(1/2-1).
(-1*2/1)+(-1/2*1/3)+(-1/3*1/4)+…+(-1/2012*1/2013)
| 1/3 - 1/2 | + | 1/4 - 1/3 | + | 1/5 - 1/4 | …… + | 1/2009
(1/2+1/3+1/4+…+2002)*(1+1/2+1/3+1/4+…1/2001)-
计算:(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/10).
