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.
(For the general form of a polynomial, see Problem 6 below.) 6. The degree of a term is the sum of the exponents of all the variables in that term. In functions of a single variable, such as x, the degree of a term is simply the exponent. Example 2. The term 5x3 is of degree 3 in the variable x. Example 3.
