stoweidlem60

Description: This lemma proves that there exists a function g as in the proof in BrosowskiDeutsh p. 91 (this parte of the proof actually spans through pages 91-92): g is in the subalgebra, and for all t in T , there is a j such that (j-4/3)*ε < f(t) <= (j-1/3)*ε and (j-4/3)*ε < g(t) < (j+1/3)*ε. Here F is used to represent f in the paper, and E is used to represent ε. (Contributed by Glauco Siliprandi, 20-Apr-2017)
