Using the method of completing the square, identify the conic section C. C. Sketch a graph of C. C. Find, foci and asymptotes (if any). Given is the polar equation r= 2 1−2cosθ. r = 2 1 − 2 cos θ.

4. Consider the polar equation r(3−kcosθ) = 4. r (3 k cos θ) = 4 For what values of the constant k k is this conic section an ellipse? Now assume that k k has the value in the middle of the interval ...
