How does one compute the location of the minimum algebraically (rather than numerically) of the following expression:
F:=((z^2+(z^2+2*z+2)^(1/2)*(z^2+1)^(1/2)+z+1)^(1/2)*(-z^2+(z^2-2*z+2)^(1/2)*(z^2+1)^(1/2)+z-1)^(1/2)-(z^2+(z^2-2*z+2)^(1/2)*(z^2+1)^(1/2)-z+1)^(1/2)*(-z^2+(z^2+2*z+2)^(1/2)*(z^2+1)^(1/2)-z-1)^(1/2)+2*z)/(2*z^2+2);

How do you stop Maple during this code execution:

proc()
x:
print(1);
goto(x);
end():

Is there some basis containing polynomials of the form x[1]^p*x[2]^q+x[2]^p*x[3]^q+x[3]^p*x[1]^q, (p,q posint)?
Are there known relationships between these?

Note: these are not the symmetric polynomials.

How does one view procedures not listed for export in modules?

Given  3000 linear equations in 3000 unknowns, with coefficients in a field of rationals with one algebraic number extension, which Maple solver would be fastest in solving the system?
