Theorem \The"o*rem\, n. [L. theorema, Gr. ? a sight,
speculation, theory, theorem, fr. ? to look at, ? a
spectator: cf. F. th['e]or[`e]me. See Theory.]
1. That which is considered and established as a principle;
hence, sometimes, a rule.
[1913 Webster]
Not theories, but theorems (?), 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]
Note: 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. See the Note under
Proposition, n., 5.
[1913 Webster]
Binomial theorem. (Math.) See under Binomial.
Negative theorem, a theorem which expresses the
impossibility of any assertion.
Particular theorem (Math.), a theorem which extends only to
a particular quantity.
Theorem of Pappus. (Math.) See Centrobaric method, under
Centrobaric.
Universal theorem (Math.), a theorem which extends to any
quantity without restriction.

Centrobaric \Cen`tro*bar"ic\, a. [Gr. (?) ? a treatise of
Archimedes on finding the center of gravity, fr. ?
gravitating toward the center; ? center + ? weight.]
Relating to the center of gravity, or to the process of
finding it.
[1913 Webster]
Centrobaric method (Math.), a process invented for the
purpose of measuring the area or the volume generated by
the rotation of a line or surface about a fixed axis,
depending upon the principle that every figure formed by
the revolution of a line or surface about such an axis has
for measure the product of the line or surface by the
length of the path of its center of gravity; -- sometimes
called theorem of Pappus, also, incorrectly, Guldinus's
properties. See Barycentric calculus, under Calculus.
