5*cos(x)
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: 5sin(x)- 5 \sin{\left(x \right)}


The answer is:

5sin(x)- 5 \sin{\left(x \right)}
