Multiplication and Inverse Matrices -- Lecture #3. How to multiply matrices and find and use inverse matrices to solve systems of linear equations.
- How do you multiply matrices?
- What is an inverse matrix?
- How do you find an inverse matrix?
- What is a nonsingular matrix?
- What is a singular matrix?
This video explains very well (though at times it can be difficult to follow) how to use inverse matrices to solve systems of equations, and why this works. Also, multiplying matrices is explained.
