Transform

Detail solution

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

      The result is: $2$
    The result of the chain rule is:
    
    $\frac{1}{\sqrt{2 x - 1}}$

  1. Let $u = 2 - 2 x$ .
  2. Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(2 - 2 x\right)$ :
    1. Differentiate $2 - 2 x$ term by term:
      
      The derivative of the constant $2$ is zero.
      
      The derivative of a constant times a function is the constant times the derivative of the function.
      
      Apply the power rule: $x$ goes to $1$

      The result is: $-2$
    The result of the chain rule is:
    
    $- \frac{1}{\sqrt{2 - 2 x}}$
  Now plug in to the quotient rule:
  
  $\frac{\frac{\sqrt{2 - 2 x}}{\sqrt{2 x - 1}} + \frac{\sqrt{2 x - 1}}{\sqrt{2 - 2 x}}}{2 - 2 x}$
Now simplify:

$\frac{\sqrt{2}}{4 \left(1 - x\right)^{\frac{3}{2}} \sqrt{2 x - 1}}$

The answer is:

$\frac{\sqrt{2}}{4 \left(1 - x\right)^{\frac{3}{2}} \sqrt{2 x - 1}}$
