[tex]\int\frac{dx}{x^4+1}[/tex]
What really frustrates me is that I've seen this integral before. I believe it involved some whacky subsitution like [tex]x=e^u[/tex], but no substitution seems to work. Partial fractions just make a mess. Trig subs seem tempting but that 4 screws everything up. Ideas?
