Determinant why
Web1. The determinant of a matrix is a special value that is calculated from a square matrix. It can help you determine whether a matrix has an inverse, find the area of a triangle, and let you know if the system of equations has a unique solution. Determinants are also used in calculus and linear algebra. Web2 days ago · Why Wisconsin Has Republicans Worried. The state’s judicial race is a possible determinant of the GOP’s 2024 prospects.
