>> Alright. At any rate, negative 2 and 30 degrees. Well, let's see. If we go 30 degrees, that's this angle but we wanna go negative 2 along that angle. Negative 2, that's the negative direction. So that means we have to extend that 30-degree angle back this way. We have to take that array and as we turn it 30 degrees here, we have to think about it extending in both directions because a distance of negative 2 means negative 2, that's out this way. You see, that would be right here. Now this pretty much tells us that the coordinates of points located on a polar coordinate plane using polar coordinates is not unique. There are a lot of ways of describing this position. One way is this 30-degree angle with a distance of negative 2. Another way would be to describe an angle of, well let's see, 180 plus 30--180 plus 30, that's 210. You see, an angle of 210 degrees and then a positive distance of 2. You see, so--and then we could describe the angle as one of any angle which is coterminal with this one. So there are really an infinite number of ways of describing positions.
