4. Find the inverse of D, D¹¹, by three different methods: a. entering D in your TI-84 calculator and raising it to the negative one power (the "x¹" button works). b. reducing the matrix [D I] to reduced echelon form. c. using the formula D-¹ = 1 adj D. Show the steps of det D finding the adjugate and the determinant. Verify that the inverses you found are all identical. If they are not, go back and fix them. 5. Show that the inverse you found is correct by calculating DD¹¹ and D¹D. What result should you get? Did you get that? 6. Solve the equation Dx = f by three different methods: a. writing the augmented matrix and reducing it to echelon form. left-multiplying by D¹¹ on both b. sides.
