Homework Help: How to find where an ellipse is centered

  1. Aug 24, 2011 #1
    My equation is x^2+(y^2/4)=1

    I need to find where it is centered. I thought that from the original ellipse equation ((x - h)^2 / a^2 + (y - k)^2 / b^2 = 1) that the center is at (h,k). But in the options for my answers, (o,o) is not available. Am i missing something here?

    What is the meaning of "not available" ?
    Definitively (0,0) is the center of the ellipse x^2+(y^2/4)=1

    Are you entering (o, o)? That's what your post shows, and you should not be using the letter o/O in place of the number 0. The center of this ellipse is at (0, 0), but if you enter (o, o) as your answer, the computer program/Web page probably won't recognize this as a valid answer.

    Also, you should be entering problems like this in the Homework and Coursework section, not in the Mathematics section.
