1+2+3+4+5+....=-1/12? 为什么无数个正数相加会是负数?
S1=1-1+1-1+1...1-S1=1-(1-1+1-1+1-1...)=1-1+1-1+1...=S1→S1=1/2S2=1-2+3-4+5-6...2S2=1-2...
S1=1-1+1-1+1...
1-S1=1-(1-1+1-1+1-1...)=1-1+1-1+1...=S1 → S1=1/2
S2=1-2+3-4+5-6...
2S2=1-2+3-4+5-6
1-2+3-4+5-6...=1-1+1-1+1...=S1=1/2 →S2=1/4
S=1+2+3+4+5+6...
S-S2=1+2+3+4+5+6
-(1-2+3-4+5-6...)=4+8+12+...=4(1+2+3...)=4S
S-S2=4S
