If →b and →c are two non-collinear unit vectors and →a is any ve – InterviewSolution

1.	If →b and →c are two non-collinear unit vectors and →a is any vector, then (→a⋅→b)→b+(→a⋅→c)→c+→a⋅(→b×→c)\|→b×→c\|2(→b×→c)=
Answer» If $\to b and \to c$ are two non-collinear unit vectors and $\to a$ is any vector, then $(\to a \cdot \to b) \to b + (\to a \cdot \to c) \to c + \frac{\to a \cdot (\to b \times \to c)}{\| \to b \times \to c \|^{2}} (\to b \times \to c) =$
