:::::If I remember right (and it's been some time), I used complex/imaginary numbers in electrical engineering, systems analysis, signal processing, vibration analysis, etc. - as [[User:KennyMac|KennyMac]] said, pretty much anything with a wave or oscillation.  (As we used to say in my engineering classes, imaginary electricity can kill you.)  DC current is real, I'm not sure AC is.  (Watts are power, not current.)  Are you saying these subjects can be covered without complex/imaginary numbers?  Again, it's been a while, but that seems odd to me.  If that's the case, why is it taught with complex numbers? --[[User:Hsmom|Hsmom]] 20:13, 14 September 2008 (EDT)
