Which point or points on the ellipse x?+4y² = 4 are furthest away from the point (0, 1)? [Hint 1: "furthest away from" means "at maximal distance from" – so this question is about maximizing something.] [Hint 2: a varying positive quantity d(x) achieves its maximum and minimum values in the same locations as (d(x))² does – and sometimes it's easier to work with the second expression.]
