What Is a 2x2 Determinant?
The determinant is a number assigned to a square matrix that indicates whether the matrix has an inverse. For 2x2 matrices it is found with a simple cross-multiplication difference.
How is it calculated?
How Is It Calculated?
For [[a, b], [c, d]], det = ad − bc
- Enter the four matrix elements.
- The difference of the diagonal products is taken.
Frequently Asked Questions
What does it mean if the determinant is zero?
If the determinant is zero, the matrix has no inverse (a singular matrix).
