conic section for class discussion

On a sheet of paper, draw an ellipse on a coordinate plane centered 
at the origin. Make sure the length of the minor axis is different from the length 
of the major axis.

a. What is the equation in standard form for your ellipse?
b. What are the coordinates for the center of the ellipse and the two focus 
points?
c. What is the semi-major axis length of your ellipse and how do you know this?
d. What is the semi-minor axis length of your ellipse and how do you know this?
e. How might the ellipse you drew be different from the ellipses of others in the 
class? How might your ellipse be similar to the ellipses of others in the class?
