Simplify the expression \(2\sin(3x)\)

Step 1 ：Using the triple-angle formula, we can rewrite \(\sin(3x)\) as \(3\sin(x) - 4\sin^3(x)\)

Step 2 ：Substitute the above expression back into the original expression, we get \(2(3\sin(x) - 4\sin^3(x))\)

Step 3 ：Then simplify the expression, we get \(6\sin(x) - 8\sin^3(x)\)
