After simplifying the trigonometric expression 2 cos (3 x) sin (3 x), we get the value as sin (6 x).

We are given the expression as:

2 cos (3 x) sin (3 x)

Now, we know the trigonometric identity as:

2 sin θ cos θ = 2 sin (2 θ)

Using this identity in the expression where θ = 3 x, we get that:

2 cos (3 x) sin (3 x) = sin ( 2 × 3 x) ( value of θ substituted in the expression)

2 cos (3 x) sin (3 x) = sin (6 x)

Therefore, after simplifying the trigonometric expression 2 cos (3 x) sin (3 x), we get the value as sin (6 x).
