This integral tests your ability to recognize a clever substitution and symmetry. The key is to pair this integral with a related one—try substituting $u = 1/x$ to create a second equation, then add them together. You'll find that the two integrals combine beautifully to isolate your original integral, turning a tricky problem into something straightforward.
