y = x² + 6 - moves the parabola 6 places up the y axis y = x² – 7 - moves the parabola 7 places down the y axis In the video, the 2D curve of the Lovell Telescope dish is a parabola.

The maximum eccentricity possible is 1, which forms not a closed orbit but a parabola, meaning the object ... we need its semimajor axis (a) and semiminor axis (b). NASA gives the semimajor ...

Off-Axis Paraboloids, also known as off-axis parabolic mirrors, are commonly used as a collimator in many optical systems, where the parabola is used to produce a collimated beam from a point source.
