ConjugateDiameter Command
From GeoGebra Manual
- ConjugateDiameter[ <Line>, <Conic> ]
- Returns the conjugate diameter of the diameter that is parallel to the given line (relative to the conic section).
- Example:
ConjugateDiameter[-4x + 5y = -2, x^2 + 4 y^2 + 2x - 8y + 1 = 0]yields line 5x + 16y = 11
- ConjugateDiameter[ <Vector>, <Conic> ]
- Returns the conjugate diameter of the diameter that is parallel to the given vector (relative to the conic section).
- Example: Let u = (4,1) be a vector. Then
ConjugateDiameter[u, x^2 + 4 y^2 + 2x - 8y + 1 = 0]yields line x + y = 0
