sandwich theorems, radiant functions, coradiant functions


We show that between two graphs, one of a radiant function and the other  of a coradiant, both dened on a real interval containing 0, there exists at  least one line which separates the graphs. The conditions for the uniqueness of a separating linear function are also established.
