Matrix and determinants are actually very useful in engineering. I am going to give you a good personal example. I am a chemical engineering student, and when I took my final this past semester for my chemical processes class one of the problems had certain substances going into a reactor and came out of the reactor as different chemicals (they reacted). As part of the procedure used to determine the mass of the outcoming materials you do a mass balance (actually I did an atomic balance because atoms can not be created nor destroyed), in my mass balance I had three equations and two unknowns. At the time I was taking an engineering math course where I learned about matrices and determinants, therefore with what I learned I placed my equations as a "system of matrices" one on top of the others and reduced to "row echelon form" and was able to find all masses individual for each of the compounds. I hope this helped, and if you have any questions dont hesitate to consult with me....Chem Boy.
A determinant is defined only for square matrices, so a 2x3 matrix does not have a determinant.Determinants are defined only for square matrices, so a 2x3 matrix does not have a determinant.
The determinant function is only defined for an nxn (i.e. square) matrix. So by definition of the determinant it would not exist for a 2x3 matrix.
To find the determinant of a matrix on a Casio fx-991MS calculator, you first need to enter the matrix into the calculator using the matrix mode. Then, navigate to the matrix menu and select the matrix you want to find the determinant of. Finally, choose the option to calculate the determinant, and the calculator will display the result. Remember that the determinant of a matrix is a scalar value that represents certain properties of the matrix.
Yes, every square matrix has a determinant. The determinant is a scalar value that can be computed from the elements of the matrix and provides important information about the matrix, such as whether it is invertible. For an ( n \times n ) matrix, the determinant can be calculated using various methods, including cofactor expansion or row reduction. However, the determinant may be zero, indicating that the matrix is singular and not invertible.
For a matrix A, A is read as determinant of A and not, as modulus of A. ... sum of two or more elements, then the given determinant can be expressed as the sum
The determinant of test is usually a scalar quantity. The determinant of a matrix is used to test whether a given matrix has an inverse or not. It is used to test for the linear dependence of the vectors.

The determinant of a 4x4 matrix can be calculated using various methods, including cofactor expansion or row reduction. The cofactor expansion involves selecting a row or column, multiplying each element by its corresponding cofactor, and summing the results. Alternatively, row reduction can simplify the matrix to an upper triangular form, where the determinant is the product of the diagonal elements, adjusted for any row swaps. The determinant provides important information about the matrix, such as whether it is invertible (non-zero determinant) or singular (zero determinant).
