SUMMARY
The discussion centers on proving the path independence of the vector field F defined as F = (4x^3y^2 + 2xy^3)i + (2x^4y - 3x^2y^2 + 4y^3)j. The curl of F was calculated and found to be zero, confirming path independence according to Stokes' theorem. The integral of F dot dr over the curve c, defined by r(t) = (t + sin(πt))i + (2t + cos(πt))j for 0 ≤ t ≤ 1, can be evaluated using a more convenient path due to this property.
