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
