1. The problem statement, all variables and given/known data Sketch the curve r = 1 + 2cosθ in polar coordinates. 2. Relevant equations None that I can think of, it's graphing. 3. The attempt at a solution What I was trying to was use the method of finding cartesian coordinates and plugging different values of θ into the equation to the the 'r' values. I came up with the graph that you can see on in the snapshot, but it looks different than the graph on my TI-89. Does it look like I am doing this correctly? Edit: So I found figured out the graph was correct, it was just a little small to scale so I increased its size so it was easier to read. I guess the only concern I have now is that I am not exactly sure what is meant by label the coordinates of three points not on either of the axes. Can someone explain to me what that part of the question is asking?
