An ALGEBRAIC function of one variable is the solution of a polynomial equation in two variables. Thus x-y**2=0 has the solution y=sqrt(x). Thus SQRT is an algebraic function. Anything that is not algebraic is TRANSCENDENTAL. I offer these comments in the spirit of mathematical nit-picking --------> Peter Monk *************************** * Dept of Math Sci * * University of Delaware * * monk@math.udel.edu * *************************** ------------------------------------------------------------
