uA- bis a ma a matrIX With eigen values y6 and-6, then the values of a and D are respectively, (Question ID = 2116] 1. 2 and-1. [Opton ID = 8463] 2. 2 and-2. [opton ID = 8464] 3. 2 and 1. [0ption ID = 8461] 4.-2 and 1. [Option 1D = 8462] Correct Answer:- 2 and-2. [Option ID = 8464] 41) 1he dimension of the vector space of all6 x6 real skew-symmetric matrices 1s [Question ID = 2126] 1. 36 [Option 1D = 8504] 2. 21 [Option ID = 8502] 3. 30 [Option ID = 8503] 4. 15 [Option ID = 8501] Correct Answer- 15 [Option ID = 8501] - ***** ****************** 42) Let (Xof (xo)) = (0, -1), (X,.f(x)) = (1, a) and (x2.f (x2)) = (2, b). If the first order divided differences f[X0, X1] = 5 and f[X1, X2]=c and the second order divided difference f[X0, X1, X2] then the values of a, b and c are [Question ID = 2148] 4, 2, 4 rOption 1D = 8592] 2, 4, 6.
