Theorem cdleme21 35625

Description: Part of proof of Lemma E in [Crawley] p. 113, 3rd line on p. 115.

represent s₂, f(s), f_s(r), t₂, f(t), f_t(r) respectively. Combine cdleme18d 35582 and cdleme21j 35624 to eliminate existence condition, proving f_s(r) = f_t(r) with fewer conditions. (Contributed by NM, 29-Nov-2012.)
