The left null space, or cokernel, of a matrix A consists of all column vectors x such that x T A = 0 T, where T denotes the transpose of a matrix. The left null space of A is the same as the kernel of A T. The left null space of A is the orthogonal complement to the column space of A, and is dual to the cokernel of the
The left null space of A is the set of all vectors x such that x T A = 0 T. It is the same as the null space of the transpose of A. The product of the matrix A T and the vector x can be written in terms of the dot product of vectors:
Henry M. Robert. A U.S. Army officer, Henry Martyn Robert (1837–1923), saw a need for a standard of parliamentary procedure while living in San Francisco.He found San Francisco in the mid-to-late 19th century to be a chaotic place where meetings of any kind tended to be tumultuous, with little consistency of procedure and with people of many nationalities and traditions thrown together.

In linear algebra, the transpose of a matrix is an operator which flips a matrix over its diagonal; that is, it switches the row and column indices of the matrix A by producing another matrix, often denoted by A T (among other notations). [1] The transpose of a matrix was introduced in 1858 by the British mathematician Arthur Cayley. [2]
The assignment produces an injective linear map between the space of linear operators from to and the space of linear operators from # to #. If X = Y {\displaystyle X=Y} then the space of linear maps is an algebra under composition of maps , and the assignment is then an antihomomorphism of algebras, meaning that t ( u v ) = t v t u ...
The following edition "supersedes all previous editions and is intended automatically to become the parliamentary authority in organizations whose bylaws prescribe "Robert's Rules of Order," "Robert's Rules of Order Revised," "Robert's Rules of Order Newly Revised," or "the current edition of" any of these titles, or the like, without specifying a particular edition."

A cheat sheet (also cheatsheet) or crib sheet is a concise set of notes used for quick reference. Cheat sheets were historically used by students without an instructor or teacher's ...
