1.	Let →b and →c be two non-collinear vectors. If →a is a vector such that →a⋅(→b+→c)=4 and a×(→b×→c)=(x2−2x+6)→b+(siny)→c, then (x,y) lies on the line
Answer» Let $\to b$ and $\to c$ be two non-collinear vectors. If $\to a$ is a vector such that $\to a \cdot (\to b + \to c) = 4$ and $a \times (\to b \times \to c) = (x^{2} - 2 x + 6) \to b + (sin y) \to c,$ then $(x, y)$ lies on the line
