White not assume the function 'solve' the values of Xa, Za and AB in the equation and thus obtain a numerical result rather than analytical in the first call? Xa=.5 Za=1 AB=1 %----------------------CÁLCULOS---------------------------------------------- % Za=1/(4*F)*Xa^2 - equation of the parabola that passes the point A(Xa,Za) % Zb=1/(4*F)*Xb^2; - equation of the parabola that passes the point B(Xb,Zb) % (Xb-Xa)^2+(Zb-Za)^2=AB^2 -equation of the circle of radius AB centered at the point A(Xa,Za) %................................................. ........................... % first call SOLVE [F,Xb,Zb]=solve('1/(4*F)*Xa^2-Za','1/(4*F)*Xb^2-Zb','(Xb-Xa)^2+(Zb-Za)^2-AB^2'); % call SOLVE with the values of Xa,Za,AB the result are numeric [F,Xb,Zb]=solve('1/(4*F)*[color=#FF0000].5[/color]^2-[color=#FF0000]1[/color]','1/(4*F)*Xb^2-Zb','(Xb-[color=#FF0000].5[/color])^2+(Zb-[color=#FF0000].5[/color])^2-[color=#FF0000]1[/color]^2'); appreciate any help ahlf
