Prove that cos2xcos2y+sin^2(x-y)-sin^2(x+y)= cos(2x+2y) |
|
Answer» To prove: cos 2θ cos2φ + sin^2 (θ – φ) – sin^2(θ + φ) = cos (2θ + 2φ) Proof: LHS = cos 2θ cos2φ + SIN2 (θ – φ) – sin2(θ + φ) = cos 2θ cos2φ + sin (θ – φ + θ + φ) sin(θ – φ - θ - φ) [Using: sin2 A - sin2 B = sin(A + B) sin (A - B)] = cos 2θ cos2φ + sin 2θ sin(-2φ) = cos 2θ cos2φ - sin 2θ sin 2φ = cos (2θ + 2φ) [using: cos (A + B) = cos A cos B - sin A sin B] = RHS [Hence PROVED] ✨Hope it will help you.✨ |
