WebIf 2sin 2 θ - cos 2 θ = 2, then find the value of θ. Solution: It is given that. 2 sin 2 θ - cos 2 θ = 2. As sin 2 θ + cos 2 θ = 1. We get cos 2 θ = 1 - sin 2 θ. 2 sin 2 θ - (1 - sin 2 θ) = 2. … WebFind the value of cos 2A, A lies in the first quadrant, when (i) cos A = 15/17 Solution : We have three formulas for cos 2A, cos 2A = cos2A - sin2A cos 2A = 1 - 2 sin2A cos 2A = 2cos2A - 1 In the above formula, let us choose the 3rd formula cos 2A = 2cos2A - 1 = 2 (15/17)2 - 1 = 2 (225/289) - 1 = (450 - 289)/289 cos 2A = 161/289 (ii) sin A = 4/5 bossanova llumi sl

Web23 nov. 2016 · sin 2A + cos 2B = 1 Squaring on both the sides Sin2 (2A)+cos2 (2B) = 1 Let us assume 2A = 2B = θ Sin2 θ +cos2 θ = 1 (Trignometric identity) Similarly, cos 2A + sin 2B Squaring on both the sides = Sin2 (2B)+cos2 (2A) = 1 Answered by: I Inamullah from Mumbai Like Answer: Given: sin 2A + cos 2B = 1........................................ ( i ) Web(i) In Terms of Cos and Sin : Sin 2A = 2 sin A cos A. Proof : We have, Sin (A + B) = sin A cos B + cos A sin B. Replacing B by A, \(\implies\) sin 2A = sin A cos A + cos A sin A … Web20 apr. 2024 · Given Equation is Sina + coseca = 2. On cubing both sides, we get (Sina + coseca)^3 = (2)^3 sin^3a + cosec^3a + 3 * sina * coseca (Sin a + coseca) = 8 sin^3a + cosec^3a + 3 * sina * 1/sina (sina + coseca) = 8 sin^3a + cosec^3a + 3 * 1 (2) = 8 sin^3a + cosec^3a + 6 = 8 sin^3a + cosec^3a = 8 - 6 sin^3a + cosec^3a = 2.
