180°-: Hence x = (R + r)cos 0 … PD = CL R + r CM = (R + r)sin^ — r sin By the nature of the hypocycloid R • 6 = r • <^, hence ^ = ^-6. x = ADr X = AL - PM = (R - r)cos e- 7- cos CPM. NowCPJ/=lSO°-</, + ^R- x=(R — r)cos 6 + r cos 180°R- Hence PD = CL - CM = (R- r)s\n O-r sin Epicycloids and hypocycloids are used in…
