✅ What Is a Determinant?
In mathematics, a determinant is a special number that can be calculated from a square matrix. For a 2×2 matrix, the formula is:
Determinant = (a × d) - (b × c)
Where the matrix looks like:
| a b |
| c d |
The determinant provides useful properties about a matrix, such as:
- Whether the matrix is invertible
- The scaling factor of transformations
- Whether a set of vectors is linearly independent
With a dedicated determinant calculator, students and professionals alike can compute this value with ease.
