    Some kind of glitch, when I posted I could not see any replies

    In fact a mental glitch, the replies were on the next page

    \int\frac{dx}{x\sqrt{x^2-1}}
    using substitution x=\frac{1}{t} in order to find integral

    i got that dx=-\frac{dt}{t^2}

    if i substitute it what should i do with denominator, especially with sqrt ?


    oh i hate it. i am going to have a test tomorrow
