So if i have the following properties, my foci, i have 0, flat, or minus 9, then my major axis, my major axis length is 22.
00:25
So we want to use this property to find the equation of an ellipse.
00:30
So let's consider a vertical major axis, major, as a.
00:43
And on the vertical major axis, we have the equation x minus h squared divided by b squared plus y minus k squared divided by a squared to be equal to one.
01:02
So for this, we know that this is equal to h k plus or minus c.
01:13
So we know h is equal to 0 here.
01:18
It means k is also equal to 0.
01:22
0.
01:23
So i see here, it's equal to 9...
