WebAnswer: The value of sin2A = 4√5/9. Example 3: If tan A = 4/3, find the value of sin2A. Solution: We have sin 2x = 2tan (x) / (1 + tan 2 (x)) So sin 2A = 2tan (A) / (1 + tan 2 (A)) Putting the value of tan A = 4/3, we get Sin 2A = 2 (4/3) / (1 + (4/3) 2) Sin2A = (8/3)/ (25/9) Sin 2A = 24/25 Answer: sin 2A = 24/25.
