The terms cat-rigged, and catboat, should not be confused with catamarans. Catamarans are not related to the term cat-rigged, though catamarans can be cat-rigged, if they have a single sail and no jib. The term 'cat' may come from the 'cat head', [citation needed] a protruding cross beam, not far behind the bow, or head, of a sailing ship, to which the anchor was attached when the vessel was preparing for sea. The mast of a cat-rigged boat is stepped near the point that the 'cat head' would be. See also. Glossary of nautical terms; References
1. Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol Â° and so ninety degrees would written 90Â°. Another unit of angle measure is the radian. 1  See Angles measured in degrees.
Degree of a polynomial. The degree of a polynomial is the highest degree of its terms when the polynomial is expressed in its canonical form consisting of a linear combination of monomials. The degree of a term is the sum of the exponents of the variables that appear in it. The term order has been used as a synonym of degree but, nowadays, may refer to several other concepts (see order of a polynomial). For example, the polynomial 7 x 2 y 3 + 4 x â 9 {\displaystyle 7x^{2}y^{3}+4x-9} has three terms.
