If `sinx+siny=sqrt(3)(cos y-cos x),` then `sin3x+sin3y=` (a)`2sin3x` (b) 0 (c) 1 (d) none of these

Explanation

To solve the equation \( \sin x + \sin y = \sqrt{3}(\cos y - \cos x) \) and find \( \sin 3x + \sin 3y \), we can follow these steps:

### Step 1: Rewrite the given equation
We start with the equation:
\[ \sin x + \sin y = \sqrt{3}(\cos y - \cos x) \]
