Margins: Functional Margin, Geometric Margin and the Width of the Street
This lesson is part of the course
In this lesson
You compare two lines that both separate the same ten tiles, measure their functional and geometric margins, and rescale the better line so that its margin width 2 ÷ ‖w‖ can be read off directly.
