In practice, one is often lead to ask questions about the geometry of a transformation: a function that takes an input and produces an output. This kind of question can be answered by linear algebra if the transformation can be expressed by a matrix. ExampleHowever, I still don't quite understand what the operator norm of a linear transformation is or what it's purpose it (other than used to define the concept of convergence in a linear space). What stumps me even more is trying to compute the operator norm of any linear transformation, for example

Linear Transformations So far we've been treating the matrix equation A x = b as simply another way of writing the vector equation x 1 a 1 + ⋯ + x n a n = b. However, we'll now think of the matrix equation in a new way: We will think of A as "acting on" the vector x to create a new vector b. For example, let's let A = [ 2 1 1 3 1 − 1].Sep 17, 2022 · In this section, we will examine some special examples of linear transformations in \(\mathbb{R}^2\) including rotations and reflections.
