find the foci and vertices of the ellipse.
x^2 y^2
--+ --=1
144 169
**
Standard form of equation for an ellipse with vertical major axis:
a>b, (h,k)=(x,y) coordinates of the center
For given equation:
center: (0,0)
a^2=169
a=√169=13
vertices:(0,0�a)=(0,�13)=(0,-13) and (0,13)
b^2=144
b=√144=12
c^2=a^2-b^2=169-144=25
c=√25=5
Foci:(0,0�c)=(0,�5)=(0,-5) and (0,5)
