(of a proportion) containing terms of which an increase in one results in a decrease in another. A term is said to be in inverse proportion to another term if it increases (or decreases) as the other decreases (or increases).
an element of an algebraic system, as a group, corresponding to a given element such that its product or sum with the given element is the identity element.
a point related to a given point so that it is situated on the same radius, extended if necessary, of a given circle or sphere and so that the product of the distances of the two points from the center equals the square of the radius of the circle or sphere.
the set of such inverses of the points of a given set, as the points on a curve.
opposite or contrary in effect, sequence, direction, etc

(of a relationship) containing two variables such that an increase in one results in a decrease in the other: the volume of a gas is in inverse ratio to its pressure
(of an element) operating on a specified member of a set to produce the identity of the set: the additive inverse element of x is –x, the multiplicative inverse element of x is 1/x

Word Origin
C17: from Latin inversus, from invertere to invert
inverse Adjective (ĭn-vûrs') Relating to a mathematical operation whose nature or effect is the opposite of another operation. For example, addition and subtraction are inverse operations, as are multiplication and division.
Noun (ĭn'vûrs')
An inverse operation. Subtraction is the inverse of addition.
Either of a pair of elements in a set whose result under the mathematical operation of the set is the identity element. For example, the inverse of 5 under multiplication is ^{1}/_{5} , since 5 × ^{1}/_{5} = 1, the identity element under multiplication. The inverse of 5 under addition is -5, since 5 + -5 = 0.
