# Convergence of $\int_{\mathbb{R}\setminus \left\{0\right\} }\frac{1}{x^2}dx$ [closed]

A doubt: With Lebesgue measure, $$\int_{\mathbb{R}\setminus \left\{0\right\} } \frac{1}{x^2}dx$$ converges?

• Can't this be decided just using improper Riemann integral on $(0,1)$? [We have an antiderivative $-1/x$ which when evaluated from $a$ to $1$ and then make $a \to 0^+$ diverges.] – coffeemath Jan 12 at 4:01
