Dual (abbreviated DU) is a grammatical number that some languages use in addition to singular and plural.When a noun or pronoun appears in dual form, it is interpreted as referring to precisely two of the entities (objects or persons) identified by the noun or pronoun acting as a single unit or in unison.
In languages with a singular/dual/plural paradigm, the exact meaning of plural depends on whether the dual is obligatory or facultative (optional). [16] In contrast to English and other singular/plural languages where plural means two or more, in languages with an obligatory dual, plural strictly means three or more.
A set C (blue) and its dual cone C * (red).. A duality in geometry is provided by the dual cone construction. Given a set of points in the plane (or more generally points in ), the dual cone is defined as the set consisting of those points (,) satisfying + for all points (,) in , as illustrated in the diagram.
Varying the dual vector in the dual problem is equivalent to revising the upper bounds in the primal problem. The lowest upper bound is sought. That is, the dual vector is minimized in order to remove slack between the candidate positions of the constraints and the actual optimum. An infeasible value of the dual vector is one that is too low.

In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is extended to bis-before a vowel; among the other monosyllables, du-, di-, dvi-, and tri-, never vary.
In addition, dual enrollment may be a cost-efficient way for students to accumulate college credits because courses are often paid for and taken through the local high school. A number of different models for dual enrollment programs exist, [7] one of which is concurrent enrollment. Concurrent enrollment is defined as credit hours earned when a ...
