Hi !
I have been editing the Hopfu.mws DE :
de1 := diff(x(t),t) = (-a + b*y(t)/(c + k*y(t)))*x(t);
de2 := diff(y(t),t) = (d - e*y(t) - f*x(t)/(c+k*y(t)))*y(t);
{a=0.5, b=1, d=1, e=1, f=1, c=0.3, k=1.0};
I managed create 2 DE equations, each in one variable, 2nd order. All efforts
were done by manual substitution... Is there a Maple package, that would do this
automatically ? Arethere more papers available about this particular DE ?
