$$\frac{x^{2}}{\sqrt{1 - x^{2}}}$$

x^2/sqrt(1 - x^2)

Detail solution

Apply the quotient rule, which is:

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

$f{\left(x \right)} = x^{2}$ and $g{\left(x \right)} = \sqrt{1 - x^{2}}$ .

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

$\frac{\frac{x^{3}}{\sqrt{1 - x^{2}}} + 2 x \sqrt{1 - x^{2}}}{1 - x^{2}}$
Now simplify:

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

The answer is:

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