8 2 1 3 4 1 0 7 2 1 let a 8 2 1 3 4 1 0 7 2 1 we know that a 1 1 a adj. Swap the positions of a and d put negatives in front of b and c and divide everything by the determinant ad bc. Let us find the inverse of a matrix by working through the following example. The inverse of a is a 1 only when a a 1 a 1 a i to find the inverse of a 2x2 matrix.

Matrices determinant of a 2 2 matrix inverse of a 3 3 matrix. 6 2 3 1 8 7 4 4 6 the nice thing about the augmented matrix approach is that it works for matrices of any size but in the case of 3xx3 matrices it is practical to calculate the adjunct matrix. Reduce the left matrix to row echelon form using elementary row operations for the whole matrix including the right one. These lessons and videos help algebra students find the inverse of a 2 2 matrix.

Consider the matrix formed by replacing each entry by the determinant of the 2xx2 matrix formed by the entries of the other rows and columns reckoned cyclically. As stated earlier finding an inverse matrix is best left to a computer especially when dealing with matrices of 4 times 4 or above. The method of calculating an inverse of a 2 times 2 and 3 times 3 matrix if one exists was also demonstrated. If a determinant of the main matrix is zero inverse doesn t exist.
