`det = (a*(e*i -f*h)) - (b*(d*i - f*g)) + (c*(d*h - e*g))`

The Determinant of a 3x3 Matrix calculator compute the determinant of a 3x3 matrix.

INSTRUCTIONS: Enter the following:

• (A) 3x3 Matrix

Determinant (det): The calculator returns the determinate as a real number.

               

Notes

The pattern continues for larger matrices: multiply a by the determinant of the matrix that is not in a's row or column, continue like this across the whole row, but remember the + - + - pattern.

Another way to calculate the determinant 3-by-3 matrix:

det(A) = a*e*i + b*f*g + c*d*h - g*e*c - h*f*a - i*d*b
