WebI also find this vector graph confusing. It contradicts this, at the end of the essay : The length of arrows drawn in a vector field are usually not to scale, but the ratio of the length of one vector to another should be accurate. The arrows near to the horizontal axis should be much shorter, to get the ratio of the lengths correct; just as the original post states. WebMaybe it would be helpful to start with simpler functions and work up. 1 input -> 1 output: to show this as a graph is simple -- you get a 2-D graph e.g. a Cartesian x-y plane where y = f (x) 2 inputs -> 1 output: these were shown in earlier videos as 3-D graphs where z = f (x,y)
