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 nature or effect or relation to another quantity ; "a term is in inverse proportion to another term if it increases (or decreases) as the other decreases (or increases)"
an opposite like you would expect, but you have to have a clear picture in your mind of what a matrix is doing to understand the inversion
The multiplicative inverse of a number, b, is 1/b.
A matrix that results from a mathematical operation on a matrix such that the two matrices can be multiplied together to obtain the unit matrix.
The daily objective of a bearish mutual fund that seeks the daily performance of increasing in value when the tracked index declines, and decreasing in value when the index rises. Buying such a bearish fund is equivalent to being short (selling short) the index. On a day the index moves up 1%, such a bearish fund should decrease by 1%. On a day the index moves down 1%, such a bearish fund should increase by 1% (all before fees and expenses).
A related but opposite process or number such as multiplication being the inverse of division and 2/1 being the inverse of 1/2.
Related but opposite operations or numbers are inverses of one another. Addition and subtraction are inverse operations. 3 is the inverse of 1/3.
