## Different Types of Ellipse Equations and Graph

Here, you will learn different types of ellipse and their basic definitions with their graphs. Let’s begin – Different Types of Ellipse (a)  First type of Ellipse is $$x^2\over a^2$$ + $$y^2\over b^2$$ = 1, where a > b   (a)  AA’ = Major axis = 2a (b)  BB’ = Minor axis = 2b (c)  …

## Equation of Ellipse in Standard Form

Equation of Ellipse in Standard Form The equation of ellipse in standard form referred to its principal axes along the coordinate axes is $$x^2\over a^2$$ + $$y^2\over b^2$$ = 1, where a > b & $$b^2$$ = $$a^2(1 – e^2)$$ $$\implies$$ $$a^2$$ – $$b^2$$ = $$a^2e^2$$. where e = eccentricity (0 < e < 1) …
