How do you graph the ellipse #(x-4)^2/8+(y-2)^2/18=1# and find the center, the major and minor axis, vertices, foci and eccentricity?
Major axis: length
Minor axis: legnth
Given the general formula
you have that:
This easily answers the question about center, axes and vertices.
For the rest, you have a formula for everything:
#c = sqrt(b^2-a^2)#(in general, major axis minus minor axis)
- Eccentricity =
#c/b#(in general, focus divided by major axis)
