yeah... this is only true when z is real though..

so do i set z:R - February 11th 2010, 08:15 PMArchie Meade

hmm ok...

just have to quick question...

1. how do u find e^i

and 2..

say you have(1+i)^i

i understand it all and it gets broken down to

exp(ilog(1+i))

but why cant it also be written as (e^logi)*(e^(1+i)) - February 12th 2010, 02:57 AMProve It
