A conservative vector field (also dubbed a path-independent vector field)is a vector ar $dlvf$ whose heat integral $dlint$ over any kind of curve $dlc$ depends only on the endpoints of $dlc$.The integral is live independence of the path that $dlc$ bring away going indigenous its starting point to its ending point. The listed below appletillustrates the two-dimensional conservative vector ar $dlvf(x,y)=(x,y)$.


The following are the values of the integrals native the suggest $vca=(3,-3)$, the beginning point of each path, come the corresponding colored suggest (i.e., the integrals follow me the highlighted part of every path). <>In the applet, the integral follow me $dlc$ is presented in blue, the integral follow me $adlc$ is displayed in green, and also the integral along $sadlc$ is shown in red. If all points are moved to the end allude $vcb=(2,4)$, climate each integral is the very same value (in this case the worth is one) since the vector field $vcF$ is conservative.

The line integral end multiple paths of a conservative vector field. The integral that conservative vector ar $dlvf(x,y)=(x,y)$ from $vca=(3,-3)$ (cyan diamond) come $vcb=(2,4)$ (magenta diamond) doesn"t rely on the path. Route $dlc$ (shown in blue) is a right line path from $vca$ to $vcb$. Courses $adlc$ (in green) and also $sadlc$ (in red) are curvy paths, but they still start at $vca$ and also end in ~ $vcb$. Every path has a colored point on it that you can drag follow me the path. The matching colored present on the slider suggest the line integral along each curve, beginning at the allude $vca$ and also ending in ~ the movable point (the integrals alone the highlighted part of each curve). Moving each point up come $vcb$ provides the full integral follow me the path, so the equivalent colored line on the slider will 1 (the magenta heat on the slider). This demonstrates the the integral is 1 independent of the path.

What are some ways to identify if a vector ar is conservative?Directly checking to see if a line integral doesn"t count on the pathis clearly impossible, together you would have to examine an infinite number of paths between any pair that points. But, if you uncovered two courses that gavedifferent values of the integral, you can conclude the vector ar was path-dependent.
