The previous section is about the hyperbolic parabolic table. This section describes the elliptical parabolic table like this.
ParabolicIt is a type of quadratic surface. There are two types of parabolic axes:Elliptical parabolicAndHyperbolic Parabolic.
The equation of an elliptical parabolic dish in the Cartesian coordinate system is:
The equation of the hyperbolic parabolic table in the flute coordinate system is:
