Determinants-Properties-Differentiation and Integration of Determinants-Class 12 Math Notes Study Material free pdf download

January 9, 2025 by Neeraj Anand, Param Anand

In linear algebra, a determinant is a special number that can be determined from a square matrix. The determinant of a matrix, say a is denoted det(a), |a| or det a. Determinants have some useful properties as they permit us to generate the same results with different and simpler entries (elements). There are 10 main properties of determinants: reflection property, all-zero property, proportionality or repetition property, switching property, scalar multiple properties, sum property, invariance property, factor property, triangle property, and co-factor matrix property. All the properties of determinants have been covered below in a detailed way, along with solved examples.

Minors and Cofactors in Matrix with Solved Examples Problems-Class 12 Math Determinants Notes Study Material free pdf download

January 9, 2025 by Neeraj Anand, Param Anand

Minors and cofactors are two of the most important concepts in matrices, as they are crucial in finding the adjoint and the inverse of a matrix. To find the determinants of a large square matrix (like 4×4), it is important to find the minors of the matrix and then the cofactors of the matrix. Below is a detailed explanation of “what minors and cofactors are”, along with steps to find them.

The adjoint of a matrix, also called the adjugate of a matrix, is defined as the transpose of the cofactor matrix of that particular matrix. For a matrix a, the adjoint is denoted as adj (a). On the other hand, the inverse of a matrix a is that matrix which, when multiplied by matrix a, gives an identity matrix. The inverse of a matrix a is denoted by a-1.
