adminsin 3 theta
Solution, When is \sin\theta > \sin 3\theta
θ and y= sin(3θ) y = sin (3 θ) in the given range are 0, π 4, 3π 4,π, 5π 4, 7π 4,2π. 0, π 4, 3 π 4, π, 5 π 4, 7 π 4, 2 π. Now looking back at our sketch, we can pinpoint the ranges where sinθ> sin3θ sin
Triple Angle Identities, Brilliant Math & Science Wiki
To prove the tripleangle identities, we can write. sin 3 θ. \sin 3 \theta sin3θ as. sin ( 2 θ + θ) \sin (2 \theta + \theta) sin(2θ+θ). Then we can use the sum formula and the doubleangle identities to

Let f (θ) = sin θ (sin θ + sin 3θ), then f (θ)
f (θ) = sin θ (sin θ + sin 3θ) = sin θ [sin θ + 3 sin θ – 4 sin 3 θ] = sin θ [4 sin θ – 4 sin 3 θ] = 4 sin 2 θ [1 – sin 2 θ] = 4 sin 2 θ cos 2 θ. = (2 sin θ cos θ) 2. f (θ) = sin 2 2θ. f (θ) > 0.
