Question

A derivada d/dx (1/x)​

Answer 1

$\displaystyle \frac{\text d}{\text{dx}}\to \frac{1}{\text x}$

$\displaystyle \frac{\text d}{\text{dx}}\to \text x^{-1}$

$\displaystyle \frac{\text d}{\text{dx}}\to \ -1.\text x^{(-1-1)}$

$\displaystyle \frac{\text d}{\text{dx}}\to -1.\text x^{(-2)}$

$\huge\boxed{\displaystyle \frac{\text d}{\text{dx}}\to \ \frac{-1}{\text x^{2}} }\checkmark$
