Boy, I've run into this! At least a third of my Algebra II Trig students have asked about this in class. A gentle reminder usually works, but they wish 1 had not been set up to mean inverse function as well as reciprocal. And I wonder why as well; there are plenty of other unused symbols. I would have suggested an upsidedown f to stand for finverse.
