उत्तर
sin2x + sin230° = 1
sin2x = 1 –sin2 30°
sin2x = 1 – `(1)/(4)`
sin2x = `(sqrt3)/(2)`
x = 60°

Solve for x : cos (2x - 30°) = 0
If A = 30°, verify that cos2θ = `(1 - tan^2 θ)/(1 + tan^2 θ)` = cos4θ - sin4θ = 2cos2θ - 1 - 2sin2θ
If θ = 30°, verify that: sin 3θ = 4sinθ . sin(60° - θ) sin(60° + θ)
