Use Newton's method to approximate, the solutions of the following system

Exemple de sortie écran :

 Use Newton's method to approximate,
 the solutions of the following system :


  | x**2 + y**2 - 1 = 0    
  | y - sin(x) = 0


 the solutions of the following system is :


         x = -0.739085  y = -0.673612  


 Open the file "a_main.plt" with gnuplot.
