System of Linear Equations & Matrices

Matrix operations

The basic operation for Matrices involve operations such as matrix addition, scalar multiplication, transposition, matrix multiplication, row operations, and submatrix.[.

As usual, I will share some youtube video that talks about this topic which I think it can help you to have an understanding of this topic.

Below is how to get the transpose of the matrix.

Determinant

The determinant of a matrix is a special number that can be calculated from a square matrix

What is it for?
1.Useful for solving linear equations
2.Use in finding the inverse of a matrix
3. And in solving the calcalus problems and many more…

Symbol
The symbol for determinant is two vertical lines either side. Example:

|A| means the determinant of the matrix A (Exactly the same symbol as absolute value.)

BASIC MATRICES

Here is some youtube video that talks about the topic that we can see so that we can have a deep understanding of the subject.
I think if you want to know more, you can just go to youtube and search matrices. Now we can learn anything with the power of the internet. So if you still not understand, don’t stop here, go and explore more.
