Can anyone direct me to learn more about polar coordinates. I'm in online college course and really am confused. In high school, I never heard of polar coordinates.
Like they say is the following the graph of point (3,15) and show it on polar grid-I don't get it at all. Please direct me somewhere to learn this or can you give me any easy explanation-thank you

Use polar coordinates to find the limit. [If (r, θ) are polar coordinates of the point (x, y) with r ≥ 0, note that r → 0+ as (x, y) → (0, 0).] (If an answer does not exist, enter DNE.) lim (x, y)→(0, 0) …
