   For parts of 'it'
   The pure 90 degree parts.

   cf as above.

   Impedance, in normal usage is the vector sum of the reactance and the
    resistance,  It applies to sine waves, and any sort of
   'waveshape'

   (It may be worth mentiong that inductoprs and capacitors are,
   at best, impure 'reactance' the capacitors come pretty close).
   Inductors all have some, sometimes substantial, resitance.)
