Mathematics

Adjoint of a matrix

आव्यूह का सहखंडज

In this Class 12 Mathematics topic from the chapter Determinants, students learn how to find the adjoint of a square matrix by calculating its cofactors and then transposing the cofactor matrix. The topic explains key properties such as A·adj(A) = |A|I and shows how the adjoint helps obtain the inverse of a matrix when its determinant is non-zero. Worked methods for small matrices strengthen calculation skills and support the solution of linear equations.
