Calculateur de 2x2 Matrix Determinant
Calculate the determinant of a 2x2 matrix.
Formula and method
This calculator computes Determinant directly in your browser without sending data to an external server.
Mathematical formula
- Determinant:
a × d-b × c
Variables and parameters
- a (row1,col1) (a): default value 1.
- b (row1,col2) (b): default value 2.
- c (row2,col1) (c): default value 3.
- d (row2,col2) (d): default value 4.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
