Nooo! In fact, all we can say is x = \int cos g(s) ds, y = \int sin g(s) ds, which in general won't be integrable in terms of elementary functions.
At this point, I'd suggest reaching for a numerical integrator. But if you want to press on, there's things called Fresnel and Lommel functions ... WFL
Thank you very much for your explanation. Integrating numerically is what I was looking to do--I have found some interesting artifacts integrating the Fresnel functions numerically and wanted to try with other curves.
