Using Matrices to Solve Systems of EquationsPosted by: raysmithtx Post date: March 21st, 2010
WEBSITE: www.teachertube.com http This video shows how to use matrices to solve systems of linear equations on the TI83 and TI84 series of graphing calculators. There is a historical snippet. The matrix arrays are shown. It shows how systems of equations in standard form and the keystroke by keystroke process of entering the equaitons into the calculator calculating the solution and interpreting the values. Checking the solution is also emphasized.
