discoverer: Katie M Find a field F(x,y) on R^2 such that at every point except the origin, F is the unit vector pointing toward the origin (the field is undefined at the origin). Write the components of F. Fx (x,y) = ?

Fy (x,y) = ?

  1. if you use polar coordinates, then what you ask is trivial f=-r^

    we can still use that but need to convert to cartesian coordinates (use Jacobian)
