Use a double-angle formula to rewrite the expression.

6 sin x cos x

Hint: sin 2a = 2 sin a cos a

so what is 3 sin 2a?

I know to use that specific formula, but I'm not sure how to incorporate it with the given.

To rewrite the expression 6 sin x cos x using a double-angle formula, we can use the formula:

sin(2θ) = 2sin(θ)cos(θ)

In this case, we can let θ = x, which means sin(2x) = 2sin(x)cos(x).

Therefore, we can rewrite the expression 6 sin x cos x as:

6 * (1/2) * sin(2x)

Simplifying further, we get:

3 sin(2x)
