Wow! 28+ hours and no one has addressed this question. Do I need to
supply more information? Have I just simply asked a really dumb
question?

I should have said a couple more things. First, when integrand
evaluates to something other than the zero function (or, at least, to
a non-constant function), the original code
var('x,y,t')
F=vector([x^2,x*y])
r=vector([cos(t), sin(t)])
tstart=0
tend=2*pi
integrand = F(x=
I borrowed/adapted the following code for carrying out a line integral
from a published notebook
var('x,y,t')
F=vector([x^2,x*y])
r=vector([cos(t), sin(t)])
tstart=0
tend=2*pi
integrand = F(x=r[0], y=r[1])*diff(r,t)
As one may observe, integrand is identically 0. The idea
