About the Parabola (from Wolfram MathWorld)
A parabola is a curve where any point is at an equal distance from a fixed point (the focus), and a fixed straight line (the directrix)
| \(a\) | |||||
| -5 | 0 | 5 | |||
| \(\theta\) | |||||
| -1.57 | 0 | 1.57 | |||
 | The parabola constructed here is the locus of line AB where \(a = Length(OD)\) and \(angle(AOD) = \theta\). |
Cartesian equation: \[Y^2+4\cdot X\cdot a-4\cdot a^2\]
