Not to be confused with Grammatical conjugation or Conjunctive mood. In grammar, a conjunction ( abbreviated CONJ or CNJ) is a part of speech that connects words, phrases, or clauses, which are called its conjuncts. That description is vague enough to overlap with those of other parts of speech because what constitutes a "conjunction" must be ...
These symbols are called logical connectives, logical operators, propositional operators, or, in classical logic, truth-functionalconnectives. For the rules which allow new well-formed formulas to be constructed by joining other well-formed formulas using truth-functional connectives, see well-formed formula. Logical connectives can be used to ...
propositional logic, Boolean algebra, first-order logic. ⊥ {\displaystyle \bot } denotes a proposition that is always false. The symbol ⊥ may also refer to perpendicular lines. The proposition. ⊥ ∧ P {\displaystyle \bot \wedge P} is always false since at least one of the two is unconditionally false. ∀.
In high-level computer programming and digital electronics, logical conjunction is commonly represented by an infix operator, usually as a keyword such as "AND", an algebraic multiplication, or the ampersand symbol &(sometimes doubled as in &&). Many languages also provide short-circuitcontrol structures corresponding to logical conjunction.
Archaic, dialectal, or specialized. The following prepositions are not widely used in Present-Day English. Some, such as bating and forby, are archaic and typically only used to convey the tone of a bygone era. Others, such as ayond and side, are generally used only by speakers of a particular variety of English.
The planet is said to be Cazimi, which is an ancient [clarification needed] astrological term meaning "in the heart" (of the Sun). For example, "Venus Cazimi" means Venus is in Conjunction with the Sun with an orb of less than ~0.28°. If a planet is moderately close to the Sun, the specific orb limit may depend on the particular planet.
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
A truth table is a structured representation that presents all possible combinations of truth values for the input variables of a Boolean function and their corresponding output values. A function f from A to F is a special relation, a subset of A×F, which simply means that f can be listed as a list of input-output pairs.
