The minor is the determinant of the matrix constructed by removing the row and column of a particular element. Thus, the minor of a34 is the determinant of the matrix which has all the same rows and columns, except for the 3rd row and 4th column.

What is a cofactor of a determinant?
The cofactor is the signed minor of a determinant, used to evaluate the determinant. You take the minor of the element - call that element aij - and if i + j is even, the cofactor is the minor - otherwise, it's the opposite of the minor. Thus, take the matrix, remove the row and column the element is in, and if the sum of the row number and column number is even, then there's your cofactor; otherwise, it's the additive inverse. For example, the cofactor of a34 is the determinant of the same matrix with the 3rd row and 4th column removed, and then you take the opposite (additive inverse or negative), because 3 + 4 = 7 is odd.

If two rows of a determinant are interchanged what is true of the resulting determinant?
The resulting determinate is the negative, or opposite, of the original determinant.
What is the determinant rank of the determinant of 123456 its a 2 x 3 matrix?

What is meant by the determinant of a math equation?
A single math equation does not have a determinant. A system of equations (3x3 , 4x4, etc.) will have a determinant. You can find a determinant of a system by converting the system into a corresponding matrix and finding its determinant.
If any two rows or columns of a determinant are identical the value of the determinant becomes?
The Value of the Determinant becomes 0
If two rows of a determinant are interchanged what is true of the resulting determinant?

Do all matrices have determinant?
Only square matrices have a determinant

What does determinant mean?
The term determinant is both noun and adjective. In case it is a noun, determinant means a factor that decisively affects the nature or outcome of something. If it is an adjective, determinant means serving to determine or decide something.
What is the determinant of a 2x3 matrix?
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.
If two rows of a matrix are interchanged what is true of the resulting determinant?
The determinant will change sign.
What is the determinant of a 2x1 matrix?
The determinant is only defined for square matrices.
