WebbThe easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into … WebbSolution LHS = sin 2 θ + cos 4 θ = sin 2 θ + ( cos 2 θ) 2 = sin 2 θ + ( 1 - sin 2 θ) 2 = sin 2 θ + 1 - 2 sin 2 θ + sin 4 θ = 1 - sin 2 θ + sin 4 θ = cos 2 θ + sin 4 θ = RHS Hence, LHS = RHS Concept: Trigonometric Identities Is there an error in this question or solution?
