Detail solution

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

    1. The derivative of cosine is negative sine:

      ddxcos⁡(x)=−sin⁡(x)\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}

    So, the result is: −2sin⁡(x)- 2 \sin{\left(x \right)}

The answer is:

−2sin⁡(x)- 2 \sin{\left(x \right)}
