From a point P in the plane of the curve, for which of the following conics can the maximum number of normals be drawn?
- ellipse
- circle
- parabola
- hyperbola
Correct answer: ellipse
Solution
For an ellipse, up to 4 normals can be drawn from a point (the conormal-point equation is quartic in the parameter), which is the maximum among the standard options.
