How do I find matrix A on my Ti–84+?
A Enter matrix A into your TI–84+ as a 3 × 3 matrix. To find A–1, go to the home screen; display the name for matrix A, under the “Names” menu, then push the x–1key. This is what your TI–84+ will look like just BEFORE you push ENTER to tell your calculator to find A–1.
How do you solve a linear equation on a TI-84 Plus?
Find the solution of X + 2Y + 3Z = 3 and 2X + 3Y + 4Z = 3. On the TI-84 Plus, you can solve a system of linear equations by entering the coeffi cients as elements in a matrix, and then using rref( to obtain the reduced row-echelon form. 6. Press Í to store the matrix to [C].
What is the TI-84 Plus guidebook?
The TI-84 Plus guidebook that is included with your graphing calculator has introduced you to basic TI-84 Plus operations. This guidebook covers the other featur es and capabilities of the TI-84 Plus in greater detail. Graphing
