WebA determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's ...

WebMatrix creation and basic operations. A column vector is an m-by-1 matrix, a row vector is a 1-by-n matrix, and a scalar is a 1-by-1 matrix. To define a matrix manually, use square brackets [ ] to denote the beginning and end of the array. Within the brackets, use a semicolon ; to denote the end of a row. In the case of a scalar (1-by-1 matrix), the … WebExpanding Pairs of Brackets. In this article we are going to have a quick look at how to expand pairs of brackets such as (x + 1)(x + 3) or (x − 5)(3x + 2). This is an important skill in high school/GCSE maths and one which often appears in algebraic problem solving, so it's important to have a good understanding of the basics.
