Nettet25. jul. 2024 · Definition: If F is a vector field defined on D and for some scalar function f on D, then f is called a potential function for F. You can calculate all the line integrals in the domain F over any path between A and B after finding the potential function f Nettet23. mai 2014 · Integration is just a summation of values (roughly). Now next question is what values. Say $f (x,y) = 1+x^3+y^3$, now if you go along x-axis from -1 to 1, the function values will be different than going along a semicircle of unit radii with origin at center of axis system.
