Can these be used directly?

  1. Jun 5, 2007 #1
    1. The problem statement, all variables and given/known data
    2. Relevant equations
    3. The attempt at a solution


    Can I use directly these results from EM theory directly in examination paper?

    ▼.E=i(k.E)

    ▼.B=i(k.B)


    ▼xE=i(kxE)

    ▼xE=i(kxE)


    (∂/∂t)E=-iwE

    (∂/∂t)B=-iwB

    yes, why not?

    If you're asking whether you can state or derive them then thats a question for your lecturer. I would state them unless asked otherwise.
