Key Topics to Revise
1
Introduction to Conic Sections
- A conic is the locus of a point whose ratio of distances from a fixed point (focus) to a fixed line (directrix) is constant (eccentricity)
- General equation of second degree: Ax² + 2Hxy + By² + 2Gx + 2Fy + C = 0
- Classification based on eccentricity: Circle (e=0), Parabola (e=1), Ellipse (e<1), Hyperbola (e>1)
2
Circle
- Locus of points equidistant from a fixed point (center)
- Standard form: (x-h)² + (y-k)² = r² where (h,k) is center and r is radius
- General form: x² + y² + 2gx + 2fy + c = 0
3
Parabola
- Locus of points equidistant from focus and directrix (eccentricity = 1)
- Four standard forms based on orientation: y² = 4ax, y² = -4ax, x² = 4ay, x² = -4ay
- Focus and directrix are equidistant from vertex
4
Ellipse
- Locus where sum of distances from two foci is constant (eccentricity < 1)
- Standard forms: x²/a² + y²/b² = 1 (horizontal major axis when a > b)
- Major axis length = 2a, minor axis length = 2b
