Description:

Explore applications of row reduction in understanding linear transformations between two and three-dimensional spaces in this 57-minute lecture. Delve into the concepts of spanning sets and linearly independent vectors. Analyze examples of transformations where input and output spaces differ, using row reduction to obtain image plane equations. Examine linear transformations from 3D to 2D, focusing on mapping basis vectors and identifying vectors sent to zero. Practice determining spanning sets and linear independence through various examples and row reduction techniques. Gain insights into the fundamental concepts of linear algebra and their practical applications in vector spaces.
