| skew | 1. Turned or twisted to one side; situated obliquely; skewed; chiefly used in technical phrases. Skew arch, an oblique arch. 2. <geometry> 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. 3. <mathematics> Skew symmetrical determinant, a determinant in which the elements in each column of the matrix are equal to the elements of the corresponding row of the matrix with the signs changed. This requires that the numbers in the diagonal from the 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. Source: Websters Dictionary (01 Mar 1998) |
