earler you said only 3 lines, now you are saying "all these lines"
as suggested by someone earler in one of your earlier posts... I think you would find it a lot quicker to select a word and look it up in the developers help.. and you would get more benefit that way... you tend to remember things more if you have to find them by yourself rather than have everyone just tell you their version.
Select the word in the Vlide and lick on the ? icon ~ it will take you straight to the help topic on that word.
now, what more explanation would you need ?POLAR Function

Distance from the specified pt.

Command: (polar '(1 1 3.5) 0.785398 1.414214)
(2.0 2.0 3.5)
Supplying a 2D point to polar:
