Exemple de sortie écran :

 If the variables are separable,
 you can use the product of two simple integrals,
 instead of a double integral.

 See c00c.c


          (3
 Hx  = int(  (x**2) * dx = 9.000000
          (0

          (+PI
 Hy  = int(  (1) * dy = 6.283185
          (-PI


 The result is  Hx * Hy = 56.548668.
