SUMMARY
The integral of 2/((x^2)-1) can be solved using partial fractions. First, simplify the expression to 1/(x^2-1), which factors into 1/((x-1)(x+1)). This can be expressed as A/(x-1) + B/(x+1) for constants A and B. To determine A and B, multiply both sides by (x^2-1) and substitute x=1 and x=-1. Finally, integrate the resulting fractions, utilizing the integral of 1/x.
