$\frac{1}{3}\int\frac{1}{x\sqrt{9x^2-81}}dx$
Learn how to solve integrals of rational functions problems step by step online. Find the integral int(1/(3x(9x^2-81)^1/2))dx. Take the constant \frac{1}{3} out of the integral. First, factor the terms inside the radical by 9 for an easier handling. Taking the constant out of the radical. We can solve the integral \frac{1}{3}\int\frac{1}{3x\sqrt{x^2-9}}dx by applying integration method of trigonometric substitution using the substitution.
