Thread: I Need Help On Ellipses Please!

ok..so it says to write equation for ellipse that satisfies each set of conditions.
the endpoints of major axis at (3,2) & (3,-14), endpoints of minor axis at (-1,-6) & (7, -6).
HOW DO I DO THIS?

Hello, cutie!

Sorry, I have to ask this: Do you know anything about ellipses?

The general equation of al ellipse is:
. . where is the center of the ellipse
. . and and are the "x-radius" and "y-radius", respectively.

You have to locate the center, then find ("half the width")
and ("half the height") . . . and drop them into the formula.

Write equation for ellipse that satisfies each set of conditions:
the endpoints of major axis at (3,2) & (3,-14),
endpoints of minor axis at (-1,-6) & (7, -6).

I don't suppose you tried to make a sketch . . .

Code:

              |
              |   (3,2)
              |     *
    ----------+-----:------------ 
              |0    :
              |     :
              |     :
    (-1,-6) * + - - o - - - * (7,-6)
              |     :
              |     :
              |     :
              |     : 
              |     *
              |   3,-14)

Can you see that the center is at . . . and that ?
