Chapter 17, Problem 35RE

Circulation and flux Consider the following vector fields.

a.    Compute the circulation on the boundary of the region R (with counterclockwise orientation).

b.    Compute the outward flux across the boundary of R.

35.    F = r/|r|, where r = 〈x, y〉 and R is the half-annulus {(r, θ): 1 ≤ r ≤ 3, 0 ≤ θ ≤ π}
