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

x^3*(sqrt(x))^2 + sin(x)/(x^2 - 1)

Detail solution

Differentiate $x^{3} \left(\sqrt{x}\right)^{2} + \frac{\sin{\left(x \right)}}{x^{2} - 1}$ term by term:
1. Apply the product rule:
  
  $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
  
  $f{\left(x \right)} = x^{3}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
  $g{\left(x \right)} = \left(\sqrt{x}\right)^{2}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Let $u = \sqrt{x}$ .
  2. Apply the power rule: $u^{2}$ goes to $2 u$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sqrt{x}$ :
    1. Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
    The result of the chain rule is:
    
    $1$
  The result is: $x^{3} + 3 x x^{2}$
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 $g{\left(x \right)} = x^{2} - 1$ .
  
  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. Differentiate $x^{2} - 1$ term by term:
    1. The derivative of the constant $-1$ is zero.
    2. Apply the power rule: $x^{2}$ goes to $2 x$
    The result is: $2 x$
  Now plug in to the quotient rule:
  
  $\frac{- 2 x \sin{\left(x \right)} + \left(x^{2} - 1\right) \cos{\left(x \right)}}{\left(x^{2} - 1\right)^{2}}$
The result is: $x^{3} + 3 x x^{2} + \frac{- 2 x \sin{\left(x \right)} + \left(x^{2} - 1\right) \cos{\left(x \right)}}{\left(x^{2} - 1\right)^{2}}$
Now simplify:

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

The answer is:

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