comment Integral of square root of a fraction of two functions
If I substitute $ \frac{x^2-1}{x^2-4} $ with $ t^2 $ then calculating $ dt $ results in a hard-to-simplify derivative. I don't see how I could move on afterwards. Could you please show some extra steps?

comment Set membership and inclusion confusion
Thanks for the reply. As far as I understand, basically, infinitely nesting an element into a set is equal to the element itself, correct? $\{\{\{...\{1\}...\}\}\} = 1$ --- Also, I'm having a lot of trouble understanding how $\{1\} = 2$. Can you elaborate on that, please?
