( a + b) ( a − b) = a 2 − b 2 = sin A 2 sin 2 sin 2 A cos 2 B − cos 2 A sin 2 B = sin 2 A ( 1 − sin 2) − cos 2 A sin 2 B. Proceed. I will prove the result by starting with the right hand side of the identity: WebSolution The correct option is D - 16 65 Explanation for the correct option. Step 1: Find the value of cos A, sin B Given that, sin A = 4 5 and cos B = - 12 13. We know that, sin 2 θ + cos 2 θ = 1 cos A = 1 - sin 2 A = 1 - 4 5 2 = 3 5 Now the value of sin B is negative because B lies in 3rd quadrant. dr talat ghaus psychiatrist il
