Ellipse formulas
 $$c = \sqrt{a^2 - b^2}$$ Linear Eccentricity
 $$e = \dfrac{c}{a}$$ Eccentricity
 $$F_1\left(c,0\right) ~~ , ~~ F_2\left(-c,0\right)$$ Foci
 $$V_1\left(a,0\right) ~~ , ~~ V_2\left(-a,0\right)$$ Vertices
 $$C_1\left(0,a\right) ~~ , ~~ C_2\left(0,-a\right)$$ Co-vertices
examples
example 1:ex 1:
Determine the coordinates of the foci of the ellipse $$\frac{x^2}{9} + \frac{y^2}{16} = 1$$
example 2:ex 2:
Find the coordinates of the foci of the ellipse given by $$\frac{4(x-3)^2}{12} + \frac{8(y+6)^2}{20} = 1$$
example 3:ex 2:
Find the major axis of the ellipse given by $$4x^2 + 9y^2 = 36$$
