How a simple 2x2 matrix reshapes the entire plane
In short: Discover the mechanics of linear transformations. This video explains how tracking just two specific vectors allows you to predict the movement of every other point in a two-dimensional space.
The video explores the concept of a 2x2 matrix acting as a linear transformation. By identifying the new positions of the basis vectors [1,0] and [0,1], you can determine the mapping for any other vector in the plane.
