SUMMARY
This discussion focuses on applying Green's Theorem to calculate the area under one arch of a cycloid defined by the parameterization p(t) = < t-2sin(t),2-2cos(t)> for 0≤t≤2π. The correct area is determined to be 8π, achieved by selecting the appropriate force field, either F=<0,x> or F = <-y,0>. The key takeaway is that while both force fields can be used, the accuracy of the integral calculation is crucial, as demonstrated by the miscalculation of the integral of t*sin(t) over the interval [0, 2π].
