$\int\frac{1}{x^{4}-1}dx$
Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(1/(x^3x^1/2^2-1))dx. Simplify the expression inside the integral. Factor the difference of squares x^{4}-1 as the product of two conjugated binomials. Rewrite the fraction \frac{1}{\left(x^{2}+1\right)\left(x^{2}-1\right)} in 2 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B, C, D. The first step is to multiply both sides of the equation from the previous step by \left(x^{2}+1\right)\left(x^{2}-1\right).
