A. | (1,0) |
B. | (0,1) |
C. | (1,1) |
D. | (1,-1) |
Option: D Explanation : Eigen value are roots of the equation i.e. (1 - a)2 - 1 = 0 a2 - 2a = 0 a = 0 or a = 2 when a = 0 this gives x = y when a = 2, This gives x = -y Hence, eigen vectors corresponding to 0 and 2 are Click on Discuss to view users comments. |

Option: C Explanation : For the matrix cofactors are a11= 1, a21 = -5, a12 = -2, a22 = -3 Therefore matrix by cofactors Adjoint A I A I = -3(1) - 5(2) = -3 - 10 = -13
