he resultant sine-function has the sameperiod as the component sine-functions, its amplitude is OP,its epoch angle the angle POD corresponding to the positionof P for t = 0. The resultant sine-function is y = a s\n{wt-\-6),where a^ = a^^ + a./ -\-2 ttia^ cos {61 — 62), a I sin $1 + €(,2 sin O2 *cij… … graphic interpretation of ccpuitions (1), (2), (3), (4) is shownin figures (a), (b), (c), (d), which also indicate the nu^nncr ofplotting the equations graphically. * A jointed paralklograin is used for conipoundiiig harmonic motionsof different periods in Lord Kelvins tidal clock.
