## 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) …
