Minors and cofactors

लघुक और सहगुणक

In this Class 12 Mathematics topic from the chapter Determinants, students learn how to find the minor of an element by deleting its corresponding row and column and evaluating the remaining determinant. They then use the sign factor (-1)^(i+j) to obtain the cofactor, understand the relationship between minors and cofactors, and apply these ideas to expand determinants along a row or column. The topic builds a foundation for solving determinant-based problems and finding the adjoint of a matrix.
