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

log(x) - 1/x^2

Detail solution

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

$\frac{x^{2} + 2}{x^{3}}$

The answer is:

$\frac{x^{2} + 2}{x^{3}}$
