## 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

## algebra precalculus How to solve $\sin\theta +\sin3 . Solve the equation by first using a SumtoProduct Formula. sinθ + sin3θ = 0. Steps I took: 0 = 2sinθ + 3θ 2 cosθ 3θ 2 0 = 2sin4θ 2 cos 2θ 2 0 = 2sin2θcos( θ) 0 = 2sin2θcosθ 0 = 2(2sinθcosθ)cosθ 0 = 4sinθcos2θ 0 = 4sinθ1 + cos2θ 2 0 = 4sinθ1 + 1 2sin2θ 2 0 = 4sinθ2 2sin2θ 2 0 = 8sinθ 8sin2θ 2. algebraprecalculus trigonometry. ## (sin^(3) thetacos^(3) theta)/(sin theta cos theta Solution For (sin^(3) thetacos^(3) theta)/(sin theta cos theta) (cos theta)/sqrt(1+ cot^(2) theta)2 tan theta cot theta=1 if.
