$\int\frac{1}{x^2-1}dx$
Learn how to solve problems step by step online. Integrate the function 1/xx/(x^2-1) from 2 to infinity. Multiplying fractions \frac{1}{x} \times \frac{x}{x^2-1}. Factor the difference of squares x^2-1 as the product of two conjugated binomials. Rewrite the fraction \frac{1}{\left(x+1\right)\left(x-1\right)} in 2 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B. The first step is to multiply both sides of the equation from the previous step by \left(x+1\right)\left(x-1\right).
