Learn Class 12 Math - Matrices and Determinants

The matrix and determinant both are part of maths. The matrix is termed as the numbers that are presented in a square box. There is proper order in a matrix that consists of the number of rows and the number of columns.

Operations on Matrices

• All the different kinds of operations can get implemented on the set.
• Like addition, subtraction, division, and multiplication.
• A term transpose of a matrix is also present.
• In the transpose of a matrix, the whole terms will get shifted. Like all the rows become columns, whereas all columns will become rows.

• Example:

  

Determinant of a Matrix

• When we have to calculate the determinant, it gets from the matrix.
• The determinant of matrix A is denoted by determinant A.

The inverse of a Matrix

The inverse of a matrix is considered the part of the matrix. And which is calculated by dividing the adjoint of a matrix from the determinants.

Adjoint of a matrix

When we transpose the cofactor of function elements, it is known as the adjoint of a matrix.
