Study Notes
Determinants and Matrix Properties
- A possible determinant value for a matrix can be -9.
- The equation represented is ( M ) where ( x = 6 ) and ( y = -1 ).
Matrix Operations
- Division is not considered a valid matrix operation.
- Valid matrix operations include addition, subtraction, and multiplication.
Matrix Representation
- A matrix designed to represent a system with 5 variables and 3 equations has 3 rows.
Matrix Notation
- Matrices are commonly enclosed in square brackets: [ ].
- The order of a row matrix with 6 entries is 1 x 6.
Identity Matrix
- The identity matrix functions similarly to the number 1 in multiplicative operations.
- When any matrix ( B ) is multiplied by the identity matrix, the result is the original matrix ( B ).
Matrix Addition Constraints
- It is not possible to add a square matrix with a non-square matrix.
Matrix Notation Clarity
- Proper matrix notation universally uses square brackets.
