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

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

      1. The derivative of sine is cosine:

        ddxsin(x)=cos(x)\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}

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

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


The answer is:

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