WebLets say x and y are coordinates on a map, and f (x,y) is the elevation in some hilly region. Taking the directional derivative with a unit vector is akin to getting the slope of f () in the direction of that unit vector. So if you were standing on a hill at (x,y), this derivative would define how steep the f () is at that point, in that direction.
