This online calculator may be used to calculate the determinant of a 3 by 3 matrix.
Let A be a 3 by 3 matrix given by
A = [[a , b , c] , [d , e , f] , [g , h , i]]
where [a , b , c] is the first row, [d , e , f] is the second row and [g , h , i] is the third row of the given matrix.
The determinant of matrix A is given by
det(A) = a (e i  h f)  d (b i  h c) + g (b f  e c)
How to use the calculator
1  Enter coefficients a, b, c, d, e, e, f, g, h and i and press "enter".
