Homework Statement
Consider the vector field F(r) = Φ^
(a) Calculate ∫ F⋅dl where C is a circle of radius R (oriented counterclockwise) in the xy-plane centered on the origin.
Homework Equations
maybe
Φ^ = -sinΦx^ + cosΦy^
The Attempt at a Solution
not really a solution. i am just stuck at what "dl" should be. if i go by my notes the "dl" is equal ∂l/∂θ (θ). but in our example its in terms of θ. so i don't know if "dl" here is equal to -sinΦx^ + cosΦy^. but can i evaluate the integral from 0 to 2π with Φ and not θ.
thanks.
