Let f(x,y) = xy. Then define the vector field F→(x,y) = ∇→ f(x,y). Sketch the vector field F→(x,y) by drawing vectors at the (m,n) where m and n are integers between -2 and 2 (inclusive). That is, draw the vectors at each grid point shown. You can scale your vectors appropriately so that the vectors you draw don't overlap.
