me result as our former pro-cedure of giving the whole vector diagram an anti-clockwise rotation, andprojecting on to a fixed vertical line. 2. Geometrical Addition. We have seen in Fig. 474 that the momentary value is represented bythe length OB, that is, by the projection of the diameter OE on… … Fig- 475 In the following considerations we shall not trouble about momentaryvalues, but shall consider simply the maximum value, or amplitude, andthe phase of the wave. We can, naturally, use effective values instead ofmaximum values, since this simply alters the scale. The wave is…
