Re: A question about location of points on a circle


I'm not sure what you mean by "locate points". If that means finding (manually) the coordinates of a point on the circumference, then you may type Ctrl-d and this will bring up a window called "2D drawing". Select the "Get coordinates" icon and place the cursor on any point you are interested in.
