RFC Number : 154 Title : Exposition Style. Network Working Group S. Crocker Request for Comments: #154 UCLA NIC: #6759 12 May 1971 Categories: C.4 Updates: #107 Obsoletes: #132 Exposition Style As a pedagogical device for describing functions such as the one below | | +----------------- | /: | / : | / : | / : | / : | / : -----+------------------------------------ | a | where two formulae, f1 and f2, are necessary for adjoining domains but the function is continous at the boundary point, I usually write the description in the form f(x) = f1(x) for x =< a f(x) = f2(x) for x >= a The astute reader will note that the domains overlap, but that f1(a) = f2(a), so no semantic ambiguity obtains.
