The solution

You have entered [src]

  ___           
\/ x  + 2*cos(x)

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

sqrt(x) + 2*cos(x)

Detail solution

Differentiate $\sqrt{x} + 2 \cos{\left(x \right)}$ term by term:
1. Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
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: $- 2 \sin{\left(x \right)} + \frac{1}{2 \sqrt{x}}$

The answer is:

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