Answer 2

The expression you've provided is the difference between two trigonometric functions: sin(a - b) and sin(a + b).

Here's how you can calculate it:

1. Start with the trigonometric identity:

   sin(A - B) - sin(A + B) = 2sin(A)cos(B)

2. In your expression, A is "a" and B is "b," so:

   sin(a - b) - sin(a + b) = 2sin(a)cos(b)

So, the simplified expression is 2sin(a)cos(b).
