Cofactors calculator.
The co-factor of the element is denoted as Cij C i j. If the minor of the element is M ij M i j, then the co-factor of element would be: Cij = (−1)i+j)M ij C i j = ( − 1) i + j) M i j. Here first we need to find the minor of the element of the matrix and then the co-factor, to obtain the co-factor matrix. A = ⎡ ⎢⎣ a11 a12 a13 a21 a22 ...

Digite um problema Salve no caderno!So it's negative 1 minus negative 4. That's the same thing as adding a 4. So it's negative 1 plus 4. So it's going to be a positive 3. So this right over here is our true matrix of minors. And from there we can get our cofactor. We can get our cofactor matrix just by remembering a checkerboard pattern.

In math, a vector is an object that has both a magnitude and a direction. Vectors are often represented by directed line segments, with an initial point and a terminal point. The length of the line segment represents the magnitude of the vector, and the arrowhead pointing in a specific direction represents the direction of the vector.

To find the determinant of a 3×3 matrix, we first need to perform some multiplication operations. For each element in the first row, we multiply that element by the determinant of the 2×2 matrix that is formed by removing the row and column of that element. This is called the "cofactor method.". Here's the formula:
