The a = %%A0 is the real root of the denominator, which then factors as: 2*s**3 - 3*s + 4 = (s - a)(2*s**2 + 2*a*s + 2*a**2 -3) The coefficients of t in the exponential functions are the roots of the quadratic factor based on the quadratic formula. Axiom should have said what %%A0 is. William _______________________________________________ Axiom-math mailing list Axiom-math@nongnu.org http://lists.nongnu.org/mailman/listinfo/axiom-math
