| Theorem | n. [ L. theorema, Gr. &unr_; a sight, speculation, theory, theorem, fr. &unr_; to look at, &unr_; a spectator: cf. F. théorème. See Theory. ] 1. That which is considered and established as a principle; hence, sometimes, a rule. [ 1913 Webster ] Not theories, but theorems (&unr_;), the intelligible products of contemplation, intellectual objects in the mind, and of and for the mind exclusively. Coleridge. [ 1913 Webster ] By the theorems,
Which your polite and terser gallants practice,
I re-refine the court, and civilize
Their barbarous natures. Massinger. [ 1913 Webster ] 2. (Math.) A statement of a principle to be demonstrated. [ 1913 Webster ] ☞ A theorem is something to be proved, and is thus distinguished from a problem, which is something to be solved. In analysis, the term is sometimes applied to a rule, especially a rule or statement of relations expressed in a formula or by symbols; as, the binomial theorem; Taylor's theorem.
