If →b and →c are non-zero and non-collinear vectors, →a×(→b× – InterviewSolution

1.	If →b and →c are non-zero and non-collinear vectors, →a×(→b×→c)+(→a⋅→b)→b=(4−2x−siny)→b+(x2−1)→c and (→c⋅→c)→a=→c. Then,
Answer» If $\to b$ and $\to c$ are non-zero and non-collinear vectors, $\to a \times (\to b \times \to c) + (\to a \cdot \to b) \to b$ $= (4 - 2 x - sin y) \to b + (x^{2} - 1) \to c$ and $(\to c \cdot \to c) \to a = \to c$ . Then,
