Find Curve for max work of a Force field

Click For Summary
SUMMARY

The discussion focuses on finding the simple closed curve that maximizes the work done by the force field F = (-4y + yx²)i - (xy²)j. Participants emphasize the application of vector calculus, particularly curved integrals and Green's Theorem, to derive the necessary conditions for maximizing work. The fundamental theorem of calculus is also highlighted as a crucial tool in this optimization process. The conclusion stresses the importance of understanding the relationship between force fields and work in the context of closed curves.

What's the definition of work (it involves an integral)? How would you go about maximizing some known function g(x,y)? Apply that to the definition of work, using the fundamental theorem of calculus.
