t the value of CR showstluit the normal does not pass through the centre of theellipse, but cuts the major axis between the centre and thefoot of the ordinate from the given point. It is, in fact, adistinct characteristic of the circle that the normal alwayspasses through the centre. 98.

In fact, the equation reduces…
