Elipse

Formula §

$\frac{(x-h{)}^2}{a^2}+\frac{(y-k{)}^2}{b^2}$ $=$ $1$

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

e = c / a (e = eccentricity, closer essentricity is to 1 the more squashed it is)

note: a value is always the bigger value so if the value under the y is bigger then that value becomes and the value under the x becomes b

Vertical Elipse §

the a is under the x hence the vertical elipse

Horizontal Elipse §

the a is under the y hence the horizontal elipse
