Meaning of Q.E.F.
Date: 8/20/96 at 11:18:17 From: Anonymous Subject: Meaning of Q.E.F. What does Q.E.F. mean? I've seen it in Euclid's Elements (Book I, postulate 1, and other places), along with Q.E.D. It seems to be things he has stated in sort of hand-wavy, "this is just how it's done," postulates, as opposed to something he had deduced directly from what he had. -David :)

As you know, Q.E.D. is the abbreviation for the Latin _quod erat demonstrandum_, "Which was to be demonstrated." Similarly, Q.E.F. is the abbreviation for _quod erat faciendum_, "Which was to be done." Your description of where it's found thus seems quite appropriate. -Doctor Sarah, The Math Forum Check out our web site! http://mathforum.org/dr.math/
