Learn how to use rref (reduced row echelon form) on a graphing calculator to solve a system of equations written as an augmented matrix.
- What is rref (reduced row echelon form) and how do you use it to reduce a matrix on a TI graphing calculator?
- How do you use the MATH > rref( function on a TI graphing calculator and what does it do?
This lesson will show you how to use reduced row echelon form on a TI graphing calculator (again, much easier on a calculator than by hand). This is very useful, especially once you get to higher math classes such as Linear Algebra.
