(1-i)/(1+i)=(1-i)^2/[(1+i)(1-i)]=(1-2i+i^2)/(1-i^2)=(1-2i-1)/(1+1)=-i (1+i)/(1-i)=[(1+i)(1+i)]/[(1-i)(1+i)]=(1+2i+i^2)/(1-i^2)=(1+2i-1)/(1+1)=i
1-i比1+i等于多少1+i比1-i等于多少为什么给我写详细点.
(1-i)/(1+i)=(1-i)^2/[(1+i)(1-i)]=(1-2i+i^2)/(1-i^2)=(1-2i-1)/(1+1)=-i (1+i)/(1-i)=[(1+i)(1+i)]/[(1-i)(1+i)]=(1+2i+i^2)/(1-i^2)=(1+2i-1)/(1+1)=i
