1det
1det is a term that appears in different contexts but does not have a single, widely accepted meaning. In mathematics, determinants are defined for square matrices, and the determinant of a 1x1 matrix [a] is simply a. There is no established mathematical concept officially called "1det"; if the term is encountered in a mathematical text, it is typically either a shorthand for the 1x1 determinant or a miscommunication rather than a standard term.
Outside mathematics, 1det may be used as a name, identifier, brand, project code, or online handle. In
Usage notes and related concepts:
- Determinant: a scalar value associated with a square matrix, with the 1x1 case equal to the matrix’s
- 1x1 matrix: the simplest square matrix, whose determinant equals its single element.
- Unimodular matrices: invertible matrices with determinant ±1, a standard concept in linear algebra.
