Find the value of f(π/3) where f(θ) = |(cos2 θ,cosθsinθ,-sinθ),(

1.	Find the value of f(π/3) where f(θ) = \|(cos2 θ,cosθsinθ,-sinθ),(cosθsinθ,sin2 θ,cosθ),(sinθ,-cosθ,0)\|
Answer» Taking cos² θ common from R₁, cosθ sinθ from R₂ and sinθ from R₃, then R₂ → R₁, R₃ → R₃ – R₁ and expand f(θ) = 1 f(π/3) = 1

Find the value of f(π/3) where f(θ) = |(cos2 θ,cosθsinθ,-sinθ),(cosθsinθ,sin2 θ,cosθ),(sinθ,-cosθ,0)|

Answer»

Taking cos² θ common from R₁, cosθ sinθ from R₂ and sinθ from R₃, then R₂ → R₁,

R₃ → R₃ – R₁ and expand

f(θ) = 1

f(π/3) = 1
