Sorry folks I owe you an apology, I meant to say amplification factor (mu) not ra 
I'm looking at RDH4 chapter 2.2, 2nd graph, I can understand why the Va scale has to be extended and I can understand the top tangent but the bottom tangent is confusing me, why is there no equal gap between the tangent line and the 6 volt -ve curve at say 120 volts either side of the 180 volt reference point?
P.S I'm not up to speed with geometry...
