comment How do I solve for the real and complex parts of an equation simultaneously?
@tair something like that, but don't forget that the real and imaginary parts may be totally different and are completely independent, so saying that you use the same equation twice is not completely true.

You shouldn't guess how to use a function, but look it up in the built-in documentation. Your suggested use of ComplexExpand is simply wrong.

comment Approximate a function of four variables with a rational polynomial
If you want to provide multiple values for each of the parameters then they are just variables. Your approximant can not automagically be valid for all possible values that they can assume. They only thing you can do is to make the procedure you use to approximate your function dependent on the parameter values so that you derive a different approximation for every set.

comment Mathematica 10 : Where is the Mathematica Book?
I see some close votes, but I don't think it is a good idea to close this question. For new users, the solutions offered in the comments are not readily found.
