WebIn general, the cofactor Cij of aij can be found by looking at all the terms in the big formula that contain aij. Cij equals (−1)i+j times the determinant of the n − 1 by n − 1 square matrix obtained by removing row i and column j. (Cij is positive if i + j is even and negative if i + j is odd.) For n × n matrices, the cofactor formula is:
