Topics in Conic Sections
Fundamental Concepts of Conic Sections
- A conic section is the locus of a point P whose distance from a fixed point (focus) bears a constant ratio (eccentricity) to its distance from a fixed line (directrix)
- Eccentricity (e) determines the type of conic: e < 1 (ellipse), e = 1 (parabola), e > 1 (hyperbola)
- Focus (S): Fixed point from which distances are measured
Parabola - Standard Forms and Properties
- Standard equation: y² = 4ax (opens rightward)
- Focus: (a, 0), Directrix: x = -a, Vertex: (0, 0)
- Axis: y = 0 (x-axis)
Parabola - Problem Solving Techniques
- Finding equation given focus and directrix: Use definition SP = PM
- Finding focus and directrix from equation: Compare with standard form
- Parametric representation: x = at², y = 2at
Ellipse - Standard Forms and Properties
- Standard equation: x²/a² + y²/b² = 1 (a > b > 0)
- Semi-major axis: a, Semi-minor axis: b
- Foci: (±ae, 0) where e² = 1 - b²/a²
