**Minors and Cofactors of a 2x2 Matrix? Yahoo Answers**

in linear algebra a rotation matrix is a matrix that is used to perform a rotation in euclidean space for example using the convention below the matrix the solution is given by the so called "determinant expansion by minors" a minor m ij of the matrix a is the n 1 by n 1 matrix made by the rows and columns of a in statistics a contingency table... 26/09/2012 · A "minor" is the determinant of the square matrix formed by deleting one row and one column from some larger square matrix. Since there are lots of rows and columns in the original matrix, you can make lots of minors from it. These minors are labeled according to the row and column you deleted. So if you were to go, say, to the a2,4 entry from some matrix A and cross out the row and …

The third step is to find the determinant of each of the 2x2 minor matrices. There is an association between each of the newly transposed 3x3 matrices with its corresponding 2x2 “minor” matrix. In order to find the right minor matrix of each of the term, you need to highlight the row and column of the term you begin with. This will include five terms of the matrix. The four other terms

at the front of the matrix. Example Find, if possible, the inverse of the matrix A = 3 2 6 4!. Solution In this case the determinant of the matrix is zero: 3 2 6 4 = 3×4− 2× 6 = 0 Because the determinant is zero the matrix is singular and no inverse exists. We explain how to ﬁnd the inverse of a 3×3 matrix in a later leaﬂet in this series. Note that a video tutorial covering the how to get rid of a unibrow with duct tape Take the minor Mrc of the matrix created earlier by omitting the elements in the row, r, and column, c, of the minor and then take the determinant of the resulting matrix. To find the minor M23 input **x(2,:)=[]** followed by **x(:,3)"=[]**. The first command deletes the second row from the matrix "x." The second command deletes the third column from the matrix "x". The sample matrix has now
