Determinants
Save
Determinants are mathematical objects that can be used to describe the behavior of linear transformations. They are used in a wide variety of applications, including solving systems of equations, finding eigenvalues and eigenvectors, and calculating volumes. There are many different ways to learn about determinants, including taking a course, reading a book, or using online resources.
What is a Determinant?
A determinant is a number that is associated with a square matrix. It is calculated by multiplying the elements of the matrix in a specific order. The determinant of a matrix can be used to determine whether the matrix is invertible, to find the eigenvalues and eigenvectors of the matrix, and to calculate the volume of the parallelepiped spanned by the columns of the matrix.
How to Calculate a Determinant
There are a number of different ways to calculate the determinant of a matrix. One common method is to use the Laplace expansion. This method involves expanding the determinant along a row or column of the matrix and then recursively calculating the determinants of the smaller matrices that result. Another method for calculating the determinant is to use the adjoint matrix. The adjoint matrix is the transpose of the cofactor matrix, and the determinant of the adjoint matrix is equal to the determinant of the original matrix.
