Question 2

The major and minor axes of an ellipse are 110mm and 80mm
respectively.  Construct:

(a)       the ellipse using focal points methods;

(b)       a tangent and a normal to the ellipse at a point p above the major axis and 30mm from the right hand end of the major axis.

OBSERVATION

This is a question on construction of ellipse using focal point method.  It
Required candidates to locate the focal points F1 and F2 and draw
smooth curves which join to form the required ellipse.  The point P is then
located to construct the normal and tangent required.

Some candidates attempted the question by avoiding the use of focal
point method required and, of course, they failed it
