HereAB→=a→andBC→=b→

AsfromthefigureCDisparalleltoFAbutintheoppositedirection so,CD→=-AB→=-a→

DEisparalleltoABbutintheoppositedirectionso,DE→=-AB→=-b→FBistheresultantofthevectorFA andABso,FB=VectorsumofFAandAB=a→+b→Weknowthatinaregularhexagon,AD=2BCso,AD→=2b→Andweknowthat,AC→+CD→=AD→SoCD→=2b→-a→-b→=b→-a→

SinceAF→=-CD→so,AF→=a→-b→AndweknowthatAD→+DE→=AE→AE→=2b→-a→
