Homework Statement
Show that if C is a positively oriented simple closed contour, then the area of the region enclosed by C can be written (1/2i)/∫C[itex]\bar{}z[/itex]dz.
Note that expression 4 Sec. 46 can be used here even though the function f(z)=[itex]\bar{}z[/itex] is not analytic anywhere.
FORMATTING NOTE: SHOULD BE Z BAR, NOT NEGATIVE Z.
Homework Equations
exspression 4 sec. 46: ∫Cf(z)dz=∫∫R(-vx-uy)dA+i∫∫R(ux-vy)dA.
