A new entry in the best title every competition:

arXiv:0810.0827: Sine function with a cosine attitude
Authors: A. D. Alhaidari

Someday I promise that I will use the phrase "an exponential function with a logarithmic attitude."

More like this

Lately, I kind of like the sci-fi feel of:

arXiv:0808.0839 (replaced) [ps, pdf, other]
Title: Phantom stars and topology change
Authors: Andrew DeBenedictis, Remo Garattini, Francisco S. N. Lobo
Comments: 19 pages, 13 figures. V2: Extended version of the paper accepted for publication in Physical Review D
Subjects: General Relativity and Quantum Cosmology (gr-qc); Astrophysics (astro-ph); High Energy Physics - Theory (hep-th)

From the abstract;

The latter vanishes at the origin whereas the derivative of the former becomes zero there.

So the latter is the derivative of the former? Or more precisely; the asymptotically sine one has a derivative that's asymptotically cosine. Whodathunk?
