Determinant \De*ter"mi*nant\, a. [L. determinans, p. pr. of
   determinare: cf. F. d['e]terminant.]
   Serving to determine or limit; determinative.

Determinant \De*ter"mi*nant\, n.
   1. That which serves to determine; that which causes
      determination.

   2. (Math.) The sum of a series of products of several
      numbers, these products being formed according to certain
      specified laws;

   Note: thus, the determinant of the nine numbers a, b, c,a',
         b', c',a'', b'', c'', is a b' c'' - a b'' c' + a' b''
         c] - a' b c'' + a'' b' c. The determinant is written by
         placing the numbers from which it is formed in a square
         between two vertical lines. The theory of determinants
         forms a very important branch of modern mathematics.

   3. (Logic) A mark or attribute, attached to the subject or
      predicate, narrowing the extent of both, but rendering
      them more definite and precise. --Abp. Thomson.
