Simplifying the Expression sin(6a) - sin(4a)

To simplify the expression sin(6a) - sin(4a), we can use the trigonometric identity:

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

Using this identity, we can simplify the given expression as follows:

sin(6a) - sin(4a) = 2 * cos((6a + 4a)/2) * sin((6a - 4a)/2)

= 2 * cos(5a) * sin(2a)

Therefore, the simplified expression is 2 * cos(5a) * sin(2a).
