Ellipse formulas

c = a^{2} - b^{2}

Linear Eccentricity

e = \frac{c}{a}

Eccentricity

F_{1} (c, 0), F_{2} (- c, 0)

Foci

V_{1} (a, 0), V_{2} (- a, 0)

Vertices

C_{1} (0, a), C_{2} (0, - a)

Co-vertices

Examples

ex 1:

Determine the coordinates of the foci of the ellipse

\frac{x ^{2}}{9} + \frac{y ^{2}}{16} = 1

ex 2:

Find the coordinates of the foci of the ellipse given by

\frac{4 ( x - 3 ) ^{2}}{12} + \frac{8 ( y + 6 ) ^{2}}{20} = 1

ex 3:

Find the major axis of the ellipse given by

4 x^{2} + 9 y^{2} = 36
