solving complex equation
hi,
I have an EE problem and hope to make things easier with the prime. It is about complex impedances in series and parallel. I have 3 known impedances and one unkown. there is zr:=270+i*300 zt:=330j*1000 and an unkown impedance zu that result in a total impedace z:=60i*160 z is zr in parallel with the series connection of zu+zt. I was hoping that the prime could do thw magic when solving 1/z = 1/zr + 1/(zr+zu) for zu. But I get an empty result. What am I doing wrong?

RE: solving complex equation
I'm an idiot.... "use i" in cas settings seems to do the trick.
