TI-89 Calculator - 16 - Solving Systems of Equations with Matrices

[@tylerbytendorp6289]

My EE course pretty much required me to get a TI-89 so I can do matrix solving with complex numbers. Thank you so much for making these videos to help me adapt to this new calculator. All of my experience is on the TI-84 Plus.

REF is *row* echelon form, not reduced echelon form. Reduced is for the unique matrix form where the solution is easily read from the matrix.

Would you please tell me what mode - format your numbers are using? I can't seem to get rid of the decimal point for whole numbers as you are showing at the beginning of this video. Thanks!

Don't bother - I finally learned "exact"

That's gold. Thank you.
