Solved Compute The Determinant Of The Following Matrix Using Cofactor We explain how to solve the determinant of a 4x4 matrix using row operations and cofactor expansion. with examples of determinants of 4x4 matrices. This cofactor expansion calculator shows you how to find the determinant of a matrix using the method of cofactor expansion (a.k.a. laplace's expansion). Compute the determinant by cofactor expansions. a= | 1 2 5 2| | 0 0 3 0| | 2 4 3 5| | 2 0 3 5| i figured the easiest way to compute this problem would be to use a cofactor across row 2. so i got: det a = | 1 2 2| 3| 2 4 5| | 2 0 5| i went on to factor across the third row. det a = ( | 2 2| | 1 2|) 3(2| 4 5| 5| 2 4|). Learn to recognize which methods are best suited to compute the determinant of a given matrix. matrix, compute the determinant using cofactor expansions. vocabulary words: minor, cofactor. in this section, we give a recursive formula for the determinant of a matrix, called a cofactor expansion.

Explains and examples what the determinant for a 4×4 matrix is and how to use the determinant to solve systems of linear equations using minors and cofactors. Cofactors reduce the dimension of the matrices we need to find the determinant by one level. a 4 × 4 4 × 4 determinant is composed of four cofactors, each of which includes a 3 × 3 3 × 3 determinant. In this lecture you will learn an alternative method for calculating the determinant of a square matrix. this method often works well when the matrix is sparse, that is, when most of its elements are equal to 0. first we need to introduce two new concepts: minors and cofactors. a minor of a? by de nition numbers. the corresponding minor would be. Here we explain how to compute the determinant of a matrix using cofactor expansion. first you will find what minors and cofactors are (necessary to apply the cofactor expansion method), then what the cofactor expansion is about, and finally an example of the calculation of a 3×3 determinant by cofactor expansion.
