Line Integrals: Large values for grid sizes yields cluttered plot that takes a long time to construct.  If "2 dimensional" is checked, then the last components of F(x,y,z) and r(t) are ignored.  

Enter vector field:   F(x,y,z) =  ,  ,   

Enter bounds on x, y, and z : 

x min:    

 y min:     z min:       

2 dimensional 

x max:  y max:    z max:   

Axes:  

grid x:    grid y:    grid z:   
Enter r(t) for a curve C:  r(t) =    , ,

points in curve: t  in  ,
