Hi all,

need to plot the positve roots and  against so(4-->5)

restart:
assume(so,real):
m1:=5:m2:=2:m3:=1.5:a1:=0.16:a2:=0.45:a3:=0.833:d1:=0.25:d2:=0.1:d3:=0.075:
ys:=a3*d3/(m3-d3):
d:=0.5:
w3:=d*(m1-d1):w2:=d*d1*so-d*m1*so-2*a1*d*d1+a1*d*m1-a2*m1^2+a2*d1*m1+m1*m2*ys:w1:=2*a1*d*d1*so-a1*d*m1*so-a1^2*d*d1+a1*a2*d1*m1+a1*m1*m2*ys:wo:=a1^2*d*d1*so:
Q:=s->w3*s^3+w2*s^2+w1*s+wo:Q(s):
sol:=evalf(solve(Q(s),s)): S:=array([],1..3): S[1]:=sol[1];S[2]:=sol[2];S[3]:=sol[3]:
