Homework Statement
Consider two expressions (df=ydx-xdy) and (dg=ydx+xdy). One is an exact differential, the other is not. Evaluate the line integral for each over the following paths:
a) in a straight line form (1,1) to (2,2)
b) a straight line from (1,1) to (2,1), then a straight line from (2,1) to (2,2)
c) A closed loops consisting of straight lines from (1,1) to (2,1) to (2,2) to (1,1)
Homework Equations
The Attempt at a Solution
a)
Well I know dy/dx = 1, so y=x for this first equation... so I think from (1,1) to (2,2) ydx-xyd = 0? ... euh
