Chapter 4: Q49. (page 201)

The $x^{鈭� 1}$ key on a Ti-83 Plus is used to find the inverse of a matrix. If you get a SINGULAR MATRIX error on the screen, then the matrix has no inverse.
Use a graphing calculator to find inverse of each matrix.
$[\begin{matrix} 2 & 鈭� 1 \\ 1 & 鈭� 3 \end{matrix}]$

Short Answer

Expert verified

The required inverse is $[\begin{matrix} 0.6 & 鈭� 0.2 \\ 0.2 & 鈭� 0.4 \end{matrix}]$ .

Step by step solution

Step 1- Enter the matrix in the calculator

Press the $2nd$ button on the calculator after it press $x^{鈭� 1}$ then go to EDIT menu. By selecting the dimensions of matrix as $2 脳 2$ perform the insertion of the provided matrix into the calculator.

\begin{array}{l} MATRIX [A] 3 脳 3 \\ [\begin{matrix} 2 & 鈭� 1 \\ 1 & 鈭� 3 \end{matrix}] \end{array}

– Calculate the inverse

Press the $2nd$ button after the appearance of home screen by pressing $2nd$ button and MODE button. Select the matrix $[A]$ and press $x^{鈭� 1}$ to get the inverse of the matrix.

[\begin{matrix} 0.6 & - 0.2 \\ 0.2 & - 0.4 \end{matrix}]

– Make the conclusion

As the obtained matrix contains the values of provided matrix so obtained inverse is correct.
