1.	If α,β,γ,δ are the smallest positive angles in ascending order of magnitude which have their sines equal to the positive quantity k, then the value of 4 sinα2+3 sinβ2+2 sinγ2+sin δ2 is equal to
Answer» If $α, β, γ, δ$ are the smallest positive angles in ascending order of magnitude which have their sines equal to the positive quantity k, then the value of $4 s i n \frac{α}{2} + 3 s i n \frac{β}{2} + 2 s i n \frac{γ}{2} + s i n \frac{δ}{2}$ is equal to
