(log(3)*(4*x + 5))/((2*cot(sqrt(x))))

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = \left(4 x + 5\right) \log{\left(3 \right)}$ and $g{\left(x \right)} = 2 \cot{\left(\sqrt{x} \right)}$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Differentiate $4 x + 5$ term by term:
    1. The derivative of the constant $5$ is zero.
    2. 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: $4$
    The result is: $4$
  So, the result is: $4 \log{\left(3 \right)}$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. There are multiple ways to do this derivative.
    Method #1
    1. Rewrite the function to be differentiated:
      
      $\cot{\left(\sqrt{x} \right)} = \frac{1}{\tan{\left(\sqrt{x} \right)}}$
    2. Let $u = \tan{\left(\sqrt{x} \right)}$ .
    3. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
    4. Then, apply the chain rule. Multiply by $\frac{d}{d x} \tan{\left(\sqrt{x} \right)}$ :
      
      Rewrite the function to be differentiated:
      
      $\tan{\left(\sqrt{x} \right)} = \frac{\sin{\left(\sqrt{x} \right)}}{\cos{\left(\sqrt{x} \right)}}$
      
      Apply the quotient rule, which is:
      
      $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
      
      $f{\left(x \right)} = \sin{\left(\sqrt{x} \right)}$ and $g{\left(x \right)} = \cos{\left(\sqrt{x} \right)}$ .
      
      To find $\frac{d}{d x} f{\left(x \right)}$ :
      
      Let $u = \sqrt{x}$ .
      
      The derivative of sine is cosine:
      
      $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
      
      Then, apply the chain rule. Multiply by $\frac{d}{d x} \sqrt{x}$ :
      
      Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
      
      The result of the chain rule is:
      
      $\frac{\cos{\left(\sqrt{x} \right)}}{2 \sqrt{x}}$
      
      To find $\frac{d}{d x} g{\left(x \right)}$ :
      
      Let $u = \sqrt{x}$ .
      
      The derivative of cosine is negative sine:
      
      $\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$
      
      Then, apply the chain rule. Multiply by $\frac{d}{d x} \sqrt{x}$ :
      
      Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
      
      The result of the chain rule is:
      
      $- \frac{\sin{\left(\sqrt{x} \right)}}{2 \sqrt{x}}$
      
      Now plug in to the quotient rule:
      
      $\frac{\frac{\sin^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}} + \frac{\cos^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}}}{\cos^{2}{\left(\sqrt{x} \right)}}$
      
      The result of the chain rule is:
      
      $- \frac{\frac{\sin^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}} + \frac{\cos^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}}}{\cos^{2}{\left(\sqrt{x} \right)} \tan^{2}{\left(\sqrt{x} \right)}}$
    Method #2
    1. Rewrite the function to be differentiated:
      
      $\cot{\left(\sqrt{x} \right)} = \frac{\cos{\left(\sqrt{x} \right)}}{\sin{\left(\sqrt{x} \right)}}$
    2. Apply the quotient rule, which is:
      
      $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
      
      $f{\left(x \right)} = \cos{\left(\sqrt{x} \right)}$ and $g{\left(x \right)} = \sin{\left(\sqrt{x} \right)}$ .
      
      To find $\frac{d}{d x} f{\left(x \right)}$ :
      
      Let $u = \sqrt{x}$ .
      
      The derivative of cosine is negative sine:
      
      $\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$
      
      Then, apply the chain rule. Multiply by $\frac{d}{d x} \sqrt{x}$ :
      
      Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
      
      The result of the chain rule is:
      
      $- \frac{\sin{\left(\sqrt{x} \right)}}{2 \sqrt{x}}$
      
      To find $\frac{d}{d x} g{\left(x \right)}$ :
      
      Let $u = \sqrt{x}$ .
      
      The derivative of sine is cosine:
      
      $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
      
      Then, apply the chain rule. Multiply by $\frac{d}{d x} \sqrt{x}$ :
      
      Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
      
      The result of the chain rule is:
      
      $\frac{\cos{\left(\sqrt{x} \right)}}{2 \sqrt{x}}$
      
      Now plug in to the quotient rule:
      
      $\frac{- \frac{\sin^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}} - \frac{\cos^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}}}{\sin^{2}{\left(\sqrt{x} \right)}}$
  So, the result is: $- \frac{2 \left(\frac{\sin^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}} + \frac{\cos^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}}\right)}{\cos^{2}{\left(\sqrt{x} \right)} \tan^{2}{\left(\sqrt{x} \right)}}$
Now plug in to the quotient rule:

$\frac{\frac{2 \left(4 x + 5\right) \left(\frac{\sin^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}} + \frac{\cos^{2}{\left(\sqrt{x} \right)}}{2 \sqrt{x}}\right) \log{\left(3 \right)}}{\cos^{2}{\left(\sqrt{x} \right)} \tan^{2}{\left(\sqrt{x} \right)}} + 8 \log{\left(3 \right)} \cot{\left(\sqrt{x} \right)}}{4 \cot^{2}{\left(\sqrt{x} \right)}}$
Now simplify:

$\frac{\left(4 \sqrt{x} \sin{\left(2 \sqrt{x} \right)} + 4 x + 5\right) \log{\left(3 \right)}}{4 \sqrt{x} \cos^{2}{\left(\sqrt{x} \right)}}$

The answer is:

$\frac{\left(4 \sqrt{x} \sin{\left(2 \sqrt{x} \right)} + 4 x + 5\right) \log{\left(3 \right)}}{4 \sqrt{x} \cos^{2}{\left(\sqrt{x} \right)}}$
