How to Find the Standard Matrix of a Transformation: Transformations (3/4) [Passing Linear Algebra]
The columns of a transformation's standard matrix are the the vectors you get when you apply the transformation to the columns of the identity matrix. Video guide below: Both of these problems came straight from the real final exam last fall!! Problem 1: 0:45 Problem 2: 8:19 What does it mean S "composed of" U?: 11:33
