SOLUTION: In the Cartesian system, points (x, y) have a distinct representation. Why isn't this true for a point (r, Θ) in the polar coordinate system? Thanks.

What do you mean ??

What do you mean by saying that in the Cartesian system, points (x, y) have a distinct representation ??

After reading the response by Fombitz I finally understood the meaning of your post.

Surely, your formulation was wrong and reversed/inverted from inside out.


The correct formulation is this:
    In the Cartesian system, points (x, y) have a unique presentation. Why isn't this true for a point (r, Θ) in the polar coordinate system? 


In this form the question does make sense, while it doesn't make sense in your original formulation.

Comment from student: Thanks for trying to understand my problem! I'm glad you were able to understand what was meant!

My response: I was glad to understand too, after reading your formulation which was wrong and reversed/inverted from inside out.

Because of the cyclical nature of the angular coordinate so a point with an r coordinate of 1 and an angle of 30 degrees shares the same point as an r corrdinate of 1 and an angle of 390 degrees.
