Standard form of an ellipse when given the focus

The video tutorial explains how to determine the major axis of symmetry for an ellipse, whether it is vertical or horizontal. It discusses the relationship between the foci, center, and vertices, and how they lie on the major axis. The tutorial then derives the standard form of the equation for an ellipse, focusing on calculating the values of A, B, and C. Finally, it demonstrates how to finalize the equation using these calculated values.

How do you derive the values of A and B from the given major axis length?

What is the relationship between A, B, and C in the context of the major axis?

How do you calculate the value of B in the equation?
