When one circle rolls (without slipping)
on the outside of another fixed circle,a
point inside or outside the moving circle
describes a curve ,called Trochoid.
aFthe radius of fixed circle, Fthe radius
of moving circle, Fdistance of a point
from the center of movingcircle
@A point inside the moving circle (if )
A point outside the moving circle (if )
@if a, the locus is Cardioid.
