I'll give you the trig ones too.

COS	$EFEA
SIN	$EFF1
TAN	$F03A
ATN	$F09E
SQRT	$EE8D
EXP	$EF09
LOG	$E941

The FAC ($9D-A3) holds the argument and the result is returned in the
same place.

(It's been a long time since I disassembled applesoft.  Heh, that was
before I got the Merlin assembler which had its own disassembly of it.)
