Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 16.
Reika [66]
Let us assume then that the center is the origin.  If the major axis is 18, then a = 9 and a^2=81.  If the minor axis is 16, then b = 8 and b^2=64.  Now you can write the equation.  Remember that this ellipse is vertical and so a^2 goes under y^2
