im trying to figure out the integral of 1/(x^2-1).(adsbygoogle = window.adsbygoogle || []).push({});

i basically have no clue how to do this, since every thing ive tried has resulted in a dead end

i tried intergration by parts by factoring the denominator but that just results in a more complex integral.

i also tried tried multiplying both sides of the fraction by 2x and then substituting x^2-1 with u but that doesnt get anywhere either
