I have an integral in my math text that I cannot seem to tackle, help would be appreciated. thanks! I am not really sure where to start.

$\int^{1}_{0}\frac{dx}{\sqrt{log(\frac{1}{x})}}$

Try the substitution $$u = \sqrt{Log(\frac{1}{x})}$$

Before you substitute anything, remember that $\log(1/x) = - \log x$.

The substitution worked perfectly, Thanks!

I am going to pinch myself for not trying that earlier.
