If the determinant is zero, the matrix is singular, and the inverse does not exist because the transformation collapses the plane into a line or a point. Verification of Your Result.
2x2 Matrix Inverse Calculation Steps
The inverse of a matrix essentially allows you to perform division, undoing the transformation applied by the original matrix. Label the top-left element as a, the top-right as b, the bottom-left as c, and the bottom-right as d.
A 2x2 matrix can be thought of as a transformation that scales, rotates, or skews a plane. Since this is not zero, the inverse exists.
2x2 Matrix Inverse Calculation Steps
Divide these values by the determinant, negative 2. For a 2x2 matrix, this process is streamlined into a specific formula that relies on the determinant, a single number calculated from the matrix elements.
