Not really, the sin**2+cos**2 may often be more readable, and may be
hidden behind some inlined functions.

Please do not assume that "real arithmetic" optimizations have already
been performed by the programmer by hand.  And please do not
discourage people from implementing them.  If you must, insist they
are only enabled by a flag for use by those of us who want the
compiler to do such optimizations.
