Hanan grid

In geometry, the Hanan grid H(S) of a finite set S of points in the plane is obtained by constructing vertical and horizontal lines through each point in S. The main motivation for studying the Hanan grid stems from the fact that it is known to contain a minimum length rectilinear Steiner tree for S. It is named after Maurice Hanan, who was first to investigate the rectilinear Steiner minimum tree and introduced this graph. (Wikipedia).

Gridlines in nonstandard coordinate systems.

Description: We use gridlines to conveniently plot points in the standard coordinate system all the time. But in a coordinate system defined by some other basis, there is a natural analogue of coordinate systems. Learning Objectives: 1) Given a basis, sketch a few gridlines 2) Find a poi

What Exactly are Grid Lines in Coordinate Systems?

I always put up grid lines when I represent vectors or transformations in Linear Algebra. But what, exactly, are they? Now that we have established what coordinate systems are in the previous videos, I zoom in to study grid lines. This is particularly useful in funkier subspaces, say of R^
