...and K2 = Q2/V. The rotated coordinate system (x',y') is related to the coordinate system (x, y) as x' = x cos 0 + y sin 0; y' - -x sin 0 + y cos 0. (2.41) With this equation the complex signal s2 can be written as s2(z,y,t) = S2m(x,y,t)exp[i($l2t...

...orthogonal system of coordinates (x, y, z) with the z-axis along d, the equations of the rotation are x = x cos 0 — y sin 0, y = x sin 0 + y cos 6, z — z, where A(x, y, z), and A'(x, y, z). Proof. The only novelty is the last formula (4.3.4)....
