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." Perhaps I should include a zz* at the beginning of the sentence to pick up your train of thought again. Russ.
