यदि A = \beginbmatrix 1 & 0 & 0 \\ 1 & 0 & 1 \\ 0 & 1 & 0 \endbmatrix, तो सिद्ध करें कि An = An-2 + A2 - I, n ≥ 3

(b) Find the maximal linearly independent subsystem of the system of vectors :
\veca1 = (1, -1, -2), \ \veca2 = (1, 9, 3),
\veca3 = (-2, -4, 1), \ \veca4 = (3, 7, -1)
निम्न सदिश राशियों के समूह से उच्चतम संख्या का स्वतन्त्र सदिश उपसमूह प्राप्त करें :
\veca1 = (1, -1, -2), \ \veca2 = (1, 9, 3),
\veca3 = (-2, -4, 1), \ \veca4 = (3, 7, -1)
