Reading Smythe's book on static and dynamic electricity

    reading Smythe's book on "static and dynamic electricity"

    Hi,

    I am reading Smythe's book on "static and dynamic electricity" (1st edition, 1939) and I'm having trouble deriving some of the formulas. I wonder if someone already corrected that. For instance,

    1.10 - Gauss's electric flux theorem. The expression for the normal flux component has a superfluous K : [tex] dN = E_n \cdot dS[/tex]
    1.101 - I can't seem to obtain the expression for N, unless if [tex]sin^2(\alpha) = 2 \cdot (1 - cos(\alpha))[/tex] (actually : [tex] 1- cos(2\alpha) = 2 \cdot sin^2(\alpha)[/tex]).

    thanks,

    Nakis

    I suggest you try a newer high level EM book with clearer derivations than Smythe.
    No trig is needed to derive Gauss's law.

    Check your library for Griffiths.

    I personally like the Schwartz Principles of Electrodynamics. His arguements are very physical, and he more or less teaches you the basics of special relativity at a very natural point in the book; the middle, not as an afterthought.

    Griffiths is lower level than Smythe. Schwartz has a great book, but starting with SR doesn't help electrostatics. There is a new book "Classical Electromagnetism"
    by Franklin (Addison-Wesley) that is close to Smythe's (or Jackson's) level with less complication.
