ellipse
9 (x-4)^2+4 (y+2)^2=36
foci | ((4, -2-sqrt(5)) | (4, -2+sqrt(5)))=((4, -4.23607) | (4, 0.236068))
vertices | (4, -5) | (4, 1)
center | (4, -2)
semimajor axis length | 3
semiminor axis length | 2
area | 6 pi=18.8496
perimeter | 12 E(5/9)=15.8654
focal parameter | 4/sqrt(5)=1.78885
eccentricity | sqrt(5)/3=0.745356
