So the three basic steps to evaluating line integrals is:
1. Figure out the curve C, including limits.
2. Reparameterize F in terms of t.
3. Evaluate.
Sometimes, you may get the same problems with switched x(t) and y(t) values and the answers may have opposite signs of each other. Why? Try drawing out the graph and think about orientation.
Not to say that Mr. Honner didn't teach us enough, but here's a video that might help you practice more with line integrals: http://www.youtube.com/watch?v=fjEvsinvtnw . Ready for that quiz on Friday?
