Where? Where's the conic?

Generalife

For each ellipse whose equation is given below

(i) Write the equation in standard form(ii) Determine the lengths of the major and minor axes, the coordinates

of the verticies, and the coordinates of the foci.(iii) Sketch a graph of the ellipse.

Generalife

The foci of an ellipse are F1(2, 3) and F2(-2, 3), and the sum of the focal radii is 6 units. Use the definition of an ellipse to derive the equation of this ellipse.
