If then F is a conservative field, and integral doesn't depend on the path, only on the initial and final position. Also the reciprocal is true
that what my professor said to us independent of path mean the curl of the vector equal zero
but I didn't see it in the book of calculus 3) the curl is zero
this from my professor so I do not know if it is true or not but 1) and 2)
but I think it is true take this example
show that this is independent of path
is independent of path
the curl is zero or as the book solve it
and
so 6 holds for all (x,y)

Conservative vector field - Wikipedia, the free encyclopedia
they said every conservative vector is irrotational irrotational mean the curl is zero
so for example for a conservative force, divide the closed path from Po to P1, the work done on path c1 is equal to path c2 and since they are in opposite directions they sum to 0. is there any relationship to the physics sum of all paths integral? why are the conditions: positive oriented, piecewise smooth, simple closed curve necessary conditions for this and Green's Theorem?
