How do you prove that $\int^1_0 \frac{1}{\sqrt{\ln(\frac{1}{x})}}dx$ converges? I've tried more or less everything I can think of and still can't get the answer. Any hints will be appreciated!
Answer
HINT
We have that
$$\int^1_0 \frac{1}{\sqrt{\ln(\frac{1}{x})}}dx
=\int_1^\infty \frac{1}{x^2\sqrt{\ln x}}dx
=\int_1^2 \frac{1}{x^2\sqrt{\ln x}}dx+\int_2^\infty \frac{1}{x^2\sqrt{\ln x}}dx$$
and then refer to limit comparison test.
