Theorem cdleme39n 34002
Description: Part of proof of Lemma E in [Crawley] p. 113. Show that f(x) is one-to-one on  P  .\/  Q line. TODO: FIX COMMENT.  E,  Y,  G,  Z serve as f(t), f(u), ft( R), ft( S). Put hypotheses of cdleme38n 34000 in convention of cdleme32sn1awN 33968. TODO see if this hypothesis conversion would be better if done earlier. (Contributed by NM, 15-Mar-2013.)
