Topics in Parabola
Definition and Basic Properties
- A parabola is the locus of a point P such that its distance from a fixed point S (focus) equals its distance from a fixed line l (directrix)
- The eccentricity of a parabola is always 1 (e = 1)
- The axis of symmetry passes through the focus and is perpendicular to the directrix
Standard Forms and Equations
- Four standard forms based on axis orientation and opening direction
- For y² = 4ax: vertex at origin, opens rightward, focus at (a,0), directrix x = -a
- For y² = -4ax: vertex at origin, opens leftward, focus at (-a,0), directrix x = a
Shifted Parabolas and General Forms
- When vertex is at (h,k), replace x with (x-h) and y with (y-k) in standard equation
- General form: (y-k)² = 4a(x-h) for horizontal axis
- General form: (x-h)² = 4a(y-k) for vertical axis
Focal Chord Properties and Applications
- Focal chord passes through the focus of the parabola
- For parabola y² = 4ax, if focal chord has endpoints with parameters t₁ and t₂, then t₁t₂ = -1
- Length of focal chord with endpoints P(t₁) and Q(t₂) is a(t₁ + 1/t₁)²
