This is supposed to be an easy question but im still confused..
Which Polar Coordinate pairs label the same point?
a. (-2, pi/3) b. (2, -pi/3) c. (r, theta) d. (r, theta + pi) e. (-r, theta) f. (2, -2pi/3) g. (-r, theta + pi) h. (-2, 2pi/3)

Our professors gave us the answers but I want to understand how and the process. Please help

anonymous · Answer

u must graph  each point in a polar graph

anonymous · Answer

do I convert to Cartesian coordinates and then graph?

anonymous · Answer

no

anonymous · Answer

could u begging by graphing the first point?

anonymous · Answer

I tried but idk I dont think I did it right.  I'm not sure how to graph polar coordinates.. Could you show me the graph of a? then maybe I can try b?
