Find the equation in standard form of the ellipse, given the information provided.
Vertices (6, 12) and (6, −4), foci at (6, 8) and (6, 0)
**
Given info shows that ellipse has a vertical major axis
Its standard form of equation: %28x-h%29%5E2%2Fb%5E2%2B%28y-k%29%5E2%2Fa%5E2=1, a>b, (h,k)=(x,y) coordinates of center
For given ellipse:
center:(6,4)
length of vertical major axis=16 (-4 to 12)=2a
a=8
a^2=64
..
foci:
c=4 (0 to 8)/2
c^2=16
..
c^2=a^2-b^2
b^2=a^2-c^2=64-16=48
Equation of given ellipse:
%28x-6%29%5E2%2F48%2B%28y-4%29%5E2%2F64=1
