If the line →r=2^i−^j+3^k+λ(^i+^j+√2^k) makes angles α,β,γ w – InterviewSolution

1.	If the line →r=2^i−^j+3^k+λ(^i+^j+√2^k) makes angles α,β,γ with yz, xz and xy planes respectively, then sin2α+sin2β+sin2γ is
Answer» If the line $\to r = 2^i -^j + 3^k + λ (^i +^j + \sqrt{2}^k)$ makes angles $α, β, γ$ with $y z, x z$ and $x y$ planes respectively, then $s i n^{2} α + s i n^{2} β + s i n^{2} γ$ is
