Homework Statement
First off, sorry this isn't symbolized correctly. I've wrestled with this for a half hour, so here it is in crude type:
Calculate [tex]\int[/tex]c F*n ds for F(x,y)=xi+yj across the square curve C with vertices (1,1), (-1,1), (-1,-1), and (1,-1).
Homework Equations
above
The Attempt at a Solution
I've found that this can be rewritten as [tex]\int[/tex]ab F(r(t))*r'(t)) dt
I know my limits are from -1 to 1. I am having trouble parameterizing x and y. I have come up with x=t, but I don't know what y could be... y=[tex]^{+}_{-}[/tex]t?
If someone wouldn't mind explaining this problem, and how they'd attack it, I sure would appreciate the help. Thanks in advance. A step by step solution would help most, but I'll take what I can get :)
