Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Let u=3xu = 3 x.

    2. The derivative of sine is cosine:

      ddusin(u)=cos(u)\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}

    3. Then, apply the chain rule. Multiply by ddx3x\frac{d}{d x} 3 x:

      1. The derivative of a constant times a function is the constant times the derivative of the function.

        1. Apply the power rule: xx goes to 11

        So, the result is: 33

      The result of the chain rule is:

      3cos(3x)3 \cos{\left(3 x \right)}

    So, the result is: cos(3x)- \cos{\left(3 x \right)}


The answer is:

cos(3x)- \cos{\left(3 x \right)}
