Homework Statement
[tex]\int \frac{\sqrt{x^4-1}}{x^3}dx[/tex]
Homework Equations
The Attempt at a Solution
tried substituting [tex]x^4 = \sec^2 \theta[/tex] to get rid of square root but it was of no use because, I got another complex integral [tex]\int \frac{\sin^2\theta}{\cos^{\frac{3}{4}} \theta}d\theta[/tex]
Is there an easy way to solve this problem?
