An ellipse can be defined as the locus of all points that satisfy the equation x^{^}^{2} / a^{^}^{2} + y^{^}^{2} / b^{^}^{2} = 1
where:
x,y are the coordinates of any point on the ellipse,
a, b are the radius on the x and y axes respectively
PARAMETRIC EQUATION OF AN ELLIPSE
An ellipse can be defined as the locus of all points that satisfy the equations
x = a cos t
y = b sin t
where:
x,y are the coordinates of any point on the ellipse,
a, b are the radius on the x and y axes respectively,
t is the parameter, which ranges from 0 to 2π radians.
This equation is very similar to the one used to define a circle, and much of the discussion is omitted here to avoid duplication.
The only difference between the circle and the ellipse is that in a circle there is one radius, but an ellipse has two:

One radius is measured along the xaxis and is usually called a.

The other is measured along the yaxis and is usually called b.
x^{^}^{2} + y^{^}^{2} = 0, Circle x^{^}^{2} + y^{^}^{2} = r^{^}^{2}.
Ellipse x^{^}^{2} / a^{^}^{2} + y^{^}^{2} / b^{^}^{2} = 1, Ellipse x^{^}^{2} / b^{^}^{2} + y^{^}^{2} / a^{^}^{2} = 1,
Hyperbola x^{^}^{2} / a^{^}^{2} – y^{^}^{2} / b^{^}^{2} = 1. Parabola 4px = y^{^}^{2} …
