Vector and Tensor problems

  1. May 15, 2011 #1
    Hi guys and gals. I'm stuck on the following problems. Please help me out.

    1. Show that curl v is twice the local angular velocity (w), where v is the velocity vector of the fluid.

    2. Prove that I:v= div v where I is a unit tensor.

    3. Explain why alternating unit tensor is very important in order to describe the cross product of two vectors.

    4. If div E=0, div H=0, curl E=- [tex]\partial[/tex]H/[tex]\partial[/tex] t , curl H= [tex]\partial[/tex]E /[tex]\partial[/tex]t then show that E and H satisfy [tex]\nabla[/tex]2u= [tex]\partial[/tex]2u/[tex]\partial[/tex]t2
