Quasilinear equation of ellipse and hyperbola

Quasilinear equation of ellipse and hyperbola

When the focus is on the x-axis, the left and right collimator equations are: x = ± A / E, x = ± a ^ 2 / C,
When the focus is on the y-axis, the upper and lower quasilinear equations are: y = ± B / E, y = ± B ^ 2 / C
