Évaluer l'intégrale curviligne en dx.

Exemple de sortie écran :

 Evaluate the line integral :

    (
 int(   f(x,y) dx = 
    (C


 is C has the parametrization :   

 x = g(t);     y = h(t);     a < t =< b 


    (                 (b
 int( f(x,y) dx =  int( f(g(t),h(t))  g(t)' dt 
    (C                (a

Exemple de sortie écran :

 Evaluate :

    (
 int(   (x*y**2) dx = 
    (C


 is C has the parametrization :


 x = cos(t);     y = sin(t);      0.0 < t =< 1.6 


    (b
 int(   f(g(t),h(t))  g(t)' dt =  -0.250
