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)/4  + (y**2)/9  - 1 = 0    
  | ((x-1)**2)/10 + ((y+1)**2)/5 - 1 = 0


 the solutions of the following system is :


         x = -1.991565  y = -0.275244  


 Open the file "a_main.plt" with gnuplot.
