WebApr 13, 2024 · The trigonometric double angle formulas give a relationship between the basic trigonometric functions applied to twice an angle in terms of trigonometric functions of the angle itself. We can substitute the values (2x) (2x) into the sum formulas for \sin sin and \cos. cos. Using the 45-45-90 and 30-60-90 degree triangles, we can easily see the ... 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. By further simplification. 2 sin 2 θ - 1 + sin 2 θ = 2. 3 sin 2 θ = 3. Divide both sides by 3. sin 2 θ = 1. Taking square root on both sides. sin θ = 1. So we get
