## If sin A = 3/5 then find the value of sin 3A. Solution : 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 sin ³ A. sin 3A = 3 (3/5) - 4 (3/5)³ cos = COS 3 57 13. cos = COS 1500 ) 14.
