Complex numbers

Hello,

I had a little trouble in finding the solution and the how-to-solve-it of
((1-i).(1-i)^(-1) )=1

Can someone help me, please?

Kind regards,

V.

1/((1 - i )^2) = (1 - i)/( -2i )

Hello,

((1-i).(1-i)^(-1) ) = (1-i). 1/(1-i) = 1

The important thing is that you remember that (1-i)^(-1) = 1/(1-i).
