... charge is independent of the point of ref- erence. The dipolar moment is independent of the point of reference if q = 0 (pure dipol), otherwise it depends on the point of reference. Similarly one finds ... Transformation auf Diago- nalform bringen.

... function in the direction of x.Iff is a function of three variables f( x, y, z) we can form partial derivatives f ∂x , f ∂y , f ∂z which tell us the rate of change of f in three different diections. ... Griffiths and Arfken [2, 8] We have learned about the derivative df (x) dx of the function f (x) in elementary calculus. Recall that the derivative gives us the rate of change of the f...
