Determinant
(gcide) | Determinant \De*ter"mi*nant\, n.
1. That which serves to determine; that which causes
determination.
[1913 Webster]
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.

Skew arch, an oblique arch. See under Oblique.
Skew back. (Civil Engin.)
(a) The course of masonry, the stone, or the iron plate,
having an inclined face, which forms the abutment for the
voussoirs of a segmental arch.
(b) A plate, cap, or shoe, having an inclined face to receive
the nut of a diagonal brace, rod, or the end of an
inclined strut, in a truss or frame.
Skew bridge. See under Bridge, n.
Skew curve (Geom.), a curve of double curvature, or a
twisted curve. See Plane curve, under Curve.
Skew gearing, or Skew bevel gearing (Mach.), toothed
gearing, generally resembling bevel gearing, for
connecting two shafts that are neither parallel nor
intersecting, and in which the teeth slant across the
faces of the gears.
Skew surface (Geom.), a ruled surface such that in general
two successive generating straight lines do not intersect;
a warped surface; as, the helicoid is a skew surface.
Skew symmetrical determinant (Alg.), a determinant in which

upper left to lower right corner be zeros. A like
determinant in which the numbers in the diagonal are
not zeros is a skew determinant, as in (2), above.
