Given the ellipse with foci at (5,3) and (5,5) and a major axis length of 12, determine the center using ( , ) and the denominators of the equation
Center(x )^2/?, (y )^2/?=1

center is halfway between foci, at (5,1)
semimajor axis vertical, length 6
for semiminor axis, b^2 = a^2  c^2 = 3616=20
(x5)^2/20 + (y+1)^2/36 = 1
