Polar graphs and coordinates? Please help!?

Question

I have two polar graphs that I need to construct 5-point tables for....r = 6 cos (2θ) & r = 2 + 4 cos (θ). I've honestly tried to figure this out so many times and I'm pretty frusterated. I don't know how to figure out what r & θ would equal on the table. Please please please help!

Answer 1

Just make up a table of Θ and r values. Then grab 5 values for Θ, use them to compute the r, and you're done.
Remember the x,y tables you made for rectangular coordinates? This just the same only with r,Θ.
