Learn how to graph an ellipse

The video tutorial explains how to analyze and graph an ellipse by identifying its center, major and minor axes, vertices, co-vertices, and foci. The instructor guides through the process of determining these elements using formulas and graphing techniques, emphasizing the importance of visualization over memorization.

What are the coordinates of the co-vertices if the vertices are going up and down?

What is the formula used to find the distance of the foci from the center of the ellipse?

How do you approximate the value of sqrt(21) based on known square roots?
