The solution

You have entered [src]

sin(x)           
------ - 2*cos(x)
  1

$$\frac{\sin{\left(x \right)}}{1} - 2 \cos{\left(x \right)}$$

sin(x)/1 - 2*cos(x)

Detail solution

Differentiate $\frac{\sin{\left(x \right)}}{1} - 2 \cos{\left(x \right)}$ term by term:
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:
    
    $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
  So, the result is: $\cos{\left(x \right)}$
2. 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:
    
    $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
  So, the result is: $2 \sin{\left(x \right)}$
The result is: $2 \sin{\left(x \right)} + \cos{\left(x \right)}$

The answer is:

$2 \sin{\left(x \right)} + \cos{\left(x \right)}$
