Return to the matrix menu, select the letter of the matrix you chose earlier and press enter.Ĭlose the parentheses and press enter again to get the determinant. Use the right arrow key to navigate from NAMES to MATH. Set the dimensions of your matrix and press the down key after the second dimension to enter the matrix.Įnter your matrix values. Use the arrow keys to navigate to the letter you want your matrix to represent and press enter (bottom right of your calculator). Use the right arrow key to move from NAMES to EDIT.
Press the 2nd button, then the X-1 button to get to the matrix menu. Power on your calculator using the button on the bottom right. This means that its inverse does not exist ❌. If we substitute the given matrix’s values into this formula, we have the following 🔢: The formula requires that you multiply a by the determinant of the two rightmost subcolumns (efhi), b by the determinant of the outer two subcolumns (dgfi), and c by the determinant of the two rightmost subcolumns (dgeh). We’ll consider the bottom 6 terms of the matrix as 3 different subcolumns.
