Opposite in nature and effect; -- said with reference to any two operations, which, when both are performed in succession upon any quantity, reproduce that quantity; as, multiplication is the inverse operation to division. The symbol of an inverse operation is the symbol of the direct operation with -1 as an index. Thus sin-1 x means the arc or angle whose sine is x.
For addition: For any number N, its inverse (also called opposite) is a number -N so that N + (-N) = 0 (e.g., the opposite of 5 is -5, the opposite of -3/4 is 3/4). For multiplication: For any number N, its inverse (also called reciprocal) is a number N* so that N x (N*) = 1 (e.g., the reciprocal of 5 is 1/5; the reciprocal of -3/4 is -4/3.
Opposite. -5 is the additive inverse of 5, because their sum is zero. 1/3 is the multiplicative inverse of 3, because their product is 1.
Performing an algorithm exactly backwards to achieve the exact opposite of its normal effect.
Opposite in order, relation, or effect; reversed; inverted; reciprocal; -- opposed to direct.
Inverted; having a position or mode of attachment the reverse of that which is usual.
(of an operation). The operation that exactly reverses the moves involved in the operation. Take each turn backwards, and take all of the turns in reverse order. For example, the inverse of (R2- D R2 D* R2- D R2) is (R2- D- R2 D* R2- D- R2).
1) Something that is opposite, as in sequence or character; the reverse.
A type of conditional; if a conditional is p ® q, then its inverse is ~p
A new conditional formed by negating both the antecedent and the consequent of a conditional
The statement formed by negating the hypothesis and the conclusion.
