   ________
  /      2 
\/  1 - x

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

sqrt(1 - x^2)

Detail solution

Let $u = 1 - x^{2}$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
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:

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

The answer is:

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