Also we see generally that the composition of any number of simple harmonic
motions in any directions and of any periods , may be effected by adding their
components in each of any three rect . angular directions . The final resultant
motion is ...

position . Evidently the instantaneous direction of motion of B is transverse to AB ,
and of D transverse to CDhence if AB , CD produced meet in 0 , the motion of BD
