Conics how to write the equation of an ellipse given a vertex and focus

The video tutorial explains how to solve a problem involving a vertex and a focus with the center at the origin. It covers plotting the given information, handling irrational numbers, determining the major axis, and calculating the values of A, B, and C using the formula C^2 = A^2 - B^2. The tutorial emphasizes estimation techniques and understanding the relationship between the center, focus, and vertices.

What does it indicate about the major axis if one focus is above the center?

How do you derive the equation of a conic section given the values of A and B?
