Definition and Basic Properties of Ellipse
- An ellipse is the locus of a point such that the sum of its distances from two fixed points (foci) is constant
- The ratio of distance from focus to distance from directrix is constant (eccentricity e), where 0 < e < 1
- Major axis is the longest chord passing through both foci
Standard Forms of Ellipse
- Case 1: Major axis along x-axis (a > b): x²/a² + y²/b² = 1
- Case 2: Major axis along y-axis (a < b): x²/a² + y²/b² = 1
- General form: (x-h)²/a² + (y-k)²/b² = 1 with center at (h,k)
Parametric Representation
- Any point on ellipse x²/a² + y²/b² = 1 can be written as (a cos θ, b sin θ)
- θ is called eccentric angle of the point
- For ellipse with center (h,k): point is (h + a cos θ, k + b sin θ)
Tangent to Ellipse
- Equation of tangent at point (x₁, y₁) on ellipse: xx₁/a² + yy₁/b² = 1
- Tangent with slope m: y = mx ± √(a²m² + b²)
- Condition for tangency: c² = a²m² + b² for line y = mx + c
