[PATCH] trig: fix variable use in formulas

[Stephen Kitt]

The cacosh, catan, and catanh man pages include examples using a
non-existant f2 variable. Replacing the f2 references with f fixes the
examples.

Patch applied.  I edited the subject line to be:
cacosh.3, catan.3, catanh.3: EXAMPLES: Fix variable use in formulas
