If θ denote the acute angle between the line →r=(^i+2^j−^k)+λ(^i – InterviewSolution

1.	If θ denote the acute angle between the line →r=(^i+2^j−^k)+λ(^i−^j+^k) and the plane →r.(2^i−^j+^k)=4, then sinθ+√2cosθ=
Answer» If $θ$ denote the acute angle between the line $\to r = (^i + 2^j -^k) + λ (^i -^j +^k)$ and the plane $\to r . (2^i -^j +^k) = 4$ , then $sin θ + \sqrt{2} cos θ =$
