area=3D0; started=3D0;prev_x=3D0;prev_y=3D0;
add_aug(x,y)=3Dassign("area",(started)?area+(x-prev_x)*(y-prev_y)/2.+0.*=
assign("prev_x",x)+0.*assign("prev_y",y):(0.*assign("started",1)+0.*assi=
gn("prev_x",x)+0.*assign("prev_y",y)));

This should do a trapezoidal area under graph but I have not been able t=
o  =

check it's result because of time trunkage.

Anyway, plotting the return value it seems to be doing the right thing.
