For every x except 0, y represents its multiplicative inverse. The graph forms a rectangular hyperbola. In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the ...
Multiplicative inverse, the reciprocal of a number (or any other type of element for which a multiplication function is defined) Matrix inversion, an operation on a matrix that results in its multiplicative inverse; Model inversion; Set inversion
The season premiered with a movie special on April 19, 2019, with the remaining episodes set to begin airing in the fall; [6] However, all but two of the episodes premiered in 2020. [ 7 ] A thirteenth season was confirmed by Robert Tinkler , the voice actor of Delete, on X, which premiered on February 25, 2022.

Once we have defined multiplication for formal power series, we can define multiplicative inverses as follows. The multiplicative inverse of a formal power series A is a formal power series C such that AC = 1, provided that such a formal power series exists. It turns out that if A has a multiplicative inverse, it is unique, and we denote it by ...
The multiplicative identity 1 and its additive inverse −1 are always units. More generally, any root of unity in a ring R is a unit: if r n = 1, then r n−1 is a multiplicative inverse of r. In a nonzero ring, the element 0 is not a unit, so R × is not closed under addition.
The notation convention chosen here (with W 0 and W −1) follows the canonical reference on the Lambert W function by Corless, Gonnet, Hare, Jeffrey and Knuth. [3]The name "product logarithm" can be understood as follows: since the inverse function of f(w) = e w is termed the logarithm, it makes sense to call the inverse "function" of the product we w the "product logarithm".
A nonzero element of the algebra does not necessarily have a multiplicative inverse. For example, if u {\displaystyle u} is a vector in V {\displaystyle V} such that u 2 = 1 {\displaystyle u^{2}=1} , the element 1 2 ( 1 + u ) {\displaystyle \textstyle {\frac {1}{2}}(1+u)} is both a nontrivial idempotent element and a nonzero zero ...
