(20 points) Let and let C' be any simple closed curve in a plane oriented counterclockwise. Please show that the only two possible values for F. dr is 0 or-2π. (Hint) The domain of the vector field does not include the origin. Hence, the origin is seen as a hole. Consider 1) Curve C does not encompass the origin. 2) Curve C does encompass the origin. In this case, use an auxiliary curve that encompasses the origin and is encompassed...
We say that zois a source or a sink for a given flow f(2) if there exists a circle around it such that the contour integral of f(z) around this positively oriented circle is purely imaginary with imaginary part positive or respectively negative. Alternatively, we say that zois a positive or negative vortex for a given flow if there exists a circle around it such that the contour integral of f(z) around this positively oriented circle is real positive or...
