Consider the rotation field F = ⟨-y, x⟩ and the three paths shown in the figure. Compute the work done on each of the three paths. Does it appear that the line integral ∫_C F · T ds is independent of the path, where C is a path from (1,0) to (0,1)?
What is the value of the line integral for the path C1? (Type an exact answer, using π as needed.)
