11-69.
  1. Find the equation of the ellipse you would form using the same process as in problem 11-65 but with a string 15 units long.

    Extra challenge: See how far you can get rewriting it to fit the form of your result from problem 11-65. Homework Help ✎

Remember that the length of the string is the sum of the distances from each of the foci to any point on the ellipse.
