Identify an equation in standard form for ellipse with the center at the origin, vertex at (3, 0), and focus at (1, 0).
**
Standard form of equation for an ellipse with horizontal major axis:
(x-h)^2/a^2+(y-k)^2/b^2=1, a>b, (h,k) being the (x,y) coordinates of the center.
For given ellipse:
Center: (0,0)
length of horizontal major axis=6=2a (between end points of vertices)
a=3
a^2=9
c=1(from ctr to focal point)
c^2=1
c^2=a^2-b^2
b^2=a^2-c^2=9-1=8
Equation:
x^2/9+y^2/8=1
