the ellipse has a horizontal axis of the length 12 and vertical axis of the length 18.what is the equation.
**
Coordinates of the center are needed to solve this problem. I will assume they are (0,0)
Standard form of an equation for an ellipse with vertical major axis:
, a>b, (h,k)=(x,y) coordinates of center.
..
given length of vertical major axis=18=2a
a=9
a^2=81
given length of minor axis=12=2b
b=6
b^2=36
equation:
