Leave
alone the places of the two banner posts and
be the situation of the man.
In this way,
We realize that if a point moves in plane so that the amount of its separation from two fixed point is steady, then, at that point, the way is a circle and this consistent worth is equivalent to the length of the significant hub of the oval.
Then, at that point, the way depicted by the man is a circle where the length of the significant hub is
, while focuses
are the foci.
Presently let us take the beginning of the facilitate plane as the focal point of the circle, and taking the significant hub along the
The diagrammatic portrayal of the oval is as per the following:
The condition of the oval is as
, where ‘
‘ is the semi-significant hub.
Thus,
Distance between the foci
By utilizing the connection,
,we get
Henceforth, condition of the way followed by the man
