It means complex numbers are expressed in the "rectangular" form x + iy rather than in the "polar" form a.e^(i.theta).
And also, for an instance, when you type assume, w=real, which "=" symbol you used, cause I realize I cant use the normal "=" symbol.
Don't type w=real, use the symbolic menu, from where you can select "assume" and also "Modifiers" from which you can select "real" which will automatically insert an = (it's a Ctrl =).
And, when I redefine certain parameter, it says variable undefined, yet it solves it though.
The "variable undefined" error message affects the numerical solvers, but not the symbolic ones.
From your worksheet, I understand that every variable needs to be defined as real in order to solve it is it? does it has to be always real?
No they don't all have to be real, I just assumed they were real here. Without being told which are real and which aren't, the symbolic solver will often assume they could be complex. This can make it more difficult for it to find a simplified version of what you are after.

PS I've just noticed that in the file symb2 that I uploaded, I've used the wrong style "phi" in the argument list, and also have left "SRF" out of the argument list.
