Question
According to the locus definition of an ellipse, the sum of the distances from any point on the ellipse to the two fixed points (foci) is constant and equal to what?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 5 states: 'An ellipse is a curve traced by a point moving such that the sum of its distance from the two fixed points, foci, is constant and equal to the major axis.' It further clarifies: 'PF1 + PF2 = ... = AB', where AB is the major axis.
Hint
Consider the definition of the major axis in relation to the foci's properties.
