View source for Talk:Appendix B - Complex Numbers

I think when you state that y and z are the imaginary parts of a complex number, you really meant "y and d" are the imaginary parts.  I also think that the note referring to the product of complex conjugates leaves a little room for confusion when you start back up afterward with, "we call this modulus squared."  I just ended up moving the "note" down a sentence.  I think this way is more clear.  Russ.
