2       + \/ x *sin(2*x)

$$2^{\tan{\left(x \right)}} + \sqrt{x} \sin{\left(2 x \right)}$$

2^tan(x) + sqrt(x)*sin(2*x)

Detail solution

Differentiate $2^{\tan{\left(x \right)}} + \sqrt{x} \sin{\left(2 x \right)}$ term by term:
1. Let $u = \tan{\left(x \right)}$ .
2. $\frac{d}{d u} 2^{u} = 2^{u} \log{\left(2 \right)}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \tan{\left(x \right)}$ :
  1. Rewrite the function to be differentiated:
    
    $\tan{\left(x \right)} = \frac{\sin{\left(x \right)}}{\cos{\left(x \right)}}$
  2. Apply the quotient rule, which is:
    
    $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
    
    $f{\left(x \right)} = \sin{\left(x \right)}$ and $g{\left(x \right)} = \cos{\left(x \right)}$ .
    
    To find $\frac{d}{d x} f{\left(x \right)}$ :
    1. The derivative of sine is cosine:
      
      $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
    To find $\frac{d}{d x} g{\left(x \right)}$ :
    1. The derivative of cosine is negative sine:
      
      $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
    Now plug in to the quotient rule:
    
    $\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{\cos^{2}{\left(x \right)}}$
  The result of the chain rule is:
  
  $\frac{2^{\tan{\left(x \right)}} \left(\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}\right) \log{\left(2 \right)}}{\cos^{2}{\left(x \right)}}$
4. Apply the product rule:
  
  $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
  
  $f{\left(x \right)} = \sqrt{x}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
  $g{\left(x \right)} = \sin{\left(2 x \right)}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Let $u = 2 x$ .
  2. The derivative of sine is cosine:
    
    $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} 2 x$ :
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x$ goes to $1$
      So, the result is: $2$
    The result of the chain rule is:
    
    $2 \cos{\left(2 x \right)}$
  The result is: $2 \sqrt{x} \cos{\left(2 x \right)} + \frac{\sin{\left(2 x \right)}}{2 \sqrt{x}}$
The result is: $\frac{2^{\tan{\left(x \right)}} \left(\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}\right) \log{\left(2 \right)}}{\cos^{2}{\left(x \right)}} + 2 \sqrt{x} \cos{\left(2 x \right)} + \frac{\sin{\left(2 x \right)}}{2 \sqrt{x}}$
Now simplify:

$\frac{2^{\tan{\left(x \right)}} \log{\left(2 \right)}}{\cos^{2}{\left(x \right)}} + 2 \sqrt{x} \cos{\left(2 x \right)} + \frac{\sin{\left(x \right)} \cos{\left(x \right)}}{\sqrt{x}}$

The answer is:

$\frac{2^{\tan{\left(x \right)}} \log{\left(2 \right)}}{\cos^{2}{\left(x \right)}} + 2 \sqrt{x} \cos{\left(2 x \right)} + \frac{\sin{\left(x \right)} \cos{\left(x \right)}}{\sqrt{x}}$
