WebSolution : In this problem we have given the value of Sin A. Now we need to find the value of sin 3A. To solve this problem we have a formula for sin 3A.In this formula we have to plug 3/5 instead of the term sin A. Sin 3A = 3 Sin A - 4 sin³A sin 3A = 3 (3/5) - 4 (3/5)³ sin 3A = 9/5 - 4 (9/25) = 9/5 - 36/25 = (9/5) x (5/5) - 3/25 = 45/25 - 3/25 WebThe formula for sin2A is sin (A) = (1/2) * (sin A)^2.
