How do you identify the curves of polar equations?

Question

anonymous · Answer

What excitably do you mean?

anonymous · Answer

Well, I'm in Precalc, my assignment says to identify the curves of of the (given) polar equations.  I don't really know, because the notes given to me don't describe this or even polar equations in a way that I can understand.

anonymous · Answer

May I see some equations to get an idea?

anonymous · Answer

r= 1 cos(theta)

I don't understand how I type this into my calculator or anything
and @AravindG I will take a look at it, thank you.

anonymous · Answer

your equation is r = 1 cos(theta). I don't know whether there is something between 1 and cos theta or not. if just 1* costheta . is it  r = cos(theta)?. if so, it's not hard to draw the graph or explaining

anonymous · Answer

just make a table for r function respect to theta, like Zep... said, theta =0, r =1, theta =pi/2, r =0, theta = pi, r = -1.... but at the graph, the horizontal line is represent for r the vertical line is for theta move . at the end up, you have a circle with center is (0,1/2) as  usual. the radius is 1/2
