How to do matrices on a TI-89 Titanium?Posted by: raysmithtx Post date: December 13th, 2009
Can anyone please tell me how to:
1. Add /Subtract matrices
2. Multiply matrices
3. Solve augmented matrices (using rref)
using a TI-89 Titanium calculator
Please include a STEP BY STEP procedure! I got frustrated from reading the manual (which was no help) and trying to figure it out on my own. BTW I already know how to do these by hand, but our teacher wants us to know how to do them on the calculator and she doesn't know how to work a 89.
Also, please simplify because I'm noy good at following complicated procedures. Ten points to the one who does it best. THANK YOU!
