11. Given is the polar equation r= 2 1−2cosθ. r = 2 1 2 cos θ Which type of conic section does this polar equation represent: Parabola, ellipse, or hyperbola? Show that the polar equation implies the ...

The answer: polar coordinates. Yes, you thought they were just joking when they made you do stuff with polar coordinates in math class. Surprise. You actually need this sometimes. Let's do this.

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.
