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

sqrt(x^2 + 1)

Detail solution

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

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

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

The answer is:

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