Sketch the graph of the following equation. Include the directrix that corresponds to the focus at the origin. Label the vertices with appropriate polar coordinates. If the equation is an ellipse, label the center as well. - 4-4 sine Choose the correct graph below. O A. OB. O C. O D. Find the polar coordinates of significant points on the graph. Select the correct choice below and fill in the answer boxes to complete your choice (Type ordered pairs. Type exact answers, using it as needed. Use angle measures greater than or equal to 0 and less than 2nt. Use a comma to separate answers as needed.) O A. The graph is a parabola. The polar coordinates for the vertex are O B. The graph is an ellipse. The polar coordinates for the vertices are The polar coordinates for the center are
