# Math Help - fluid flow

1. ## fluid flow

given the velocity v=(x+y,x-y,0) sketch the fluid flow

is this question asking to sketch the strealimes or the trajectory anyhow i cant solve it

i guess the question is asking you to simply sketch the velocity vector field. you just have to draw velocity vectors at each point on the plane, where the the velocity at (x,y) is given by (x+y,x-y,0). of course this would be tedious to do without a software.
