I think that the following definition would 
work::

       asin x == if x = 1 then pi()/2::$ else atan(x/sqrt(1-x**2))

There is one thing that puzzles me, though. Also in 'TRANFUN', the following 
definition is given for 'pi()'::

       pi()   == 2*asin(1)

which seems to be asking for trouble. However, I couldn't find a domain that 
would use this definition for 'pi()'. Maybe it should be rather defined in 
terms of 'atan'?
