Inthis figure, as FG < FC the curve is an ellipse. Had FG been taken equal to FC, the curve would have been a… … PF 30 THE CAETESIAN METHOD OF CO-OEDINATES. The portion of the perpendicular to the directrix through the focus,CK, intercepted by the curve is the Transverse or Jfajor A-Xis^as IK. The centre of the transverse axis, O, is the centre of the curve. The perpendicular to the tranverse axis passing…
