Answered by vishwambarbk

Step-by-step explanation:

sin (A + A) = sin A cos A + sin A cos A. ⇒ sin 2A = 2 sin A cos A. Note: In the above formula we should note that the angle on the R.H.S. is half of the angle on L.H.S. Therefore, sin 60° = 2 sin 30° cos 30°. The above formula is also known as double angle formulae for sin 2A.
