Find curl v for v given with respect to right-handed Cartesian coordinates. Show the details of your work. 4. v = [2y²,5x, 0] 5. v = xyz(x, y, z) 6. v = (x²+² +22²)-3/2[x. y. 2] 7. v=0.0. e sin yl 8. v = [e=²²₁ Let v be the velocity vector of a steady fluid flow. Is the flow irrotational? Incompressible? Find the streamlines (the paths of the particles). Hint. See the answers to Probs. 9 and 11 for a determination of a path. 9. v = [0, 32²,0] 10.
