In a sense, linear transformations are an abstract description of multiplication by a matrix, as in the following example. Given a matrix A, define T(v) = Av. This is a linear transformation: A(cv) = cA(v). 1 0 Suppose A = . How would we describe the transformation T(v) = Av geometrically? y component of the vector is reversed.
Jun 19, 2024 · Find the vectors \(T\left(\twovec{1}{0}\right)\) and \(T\left(\twovec{0}{1}\right)\text{.}\) Use your results to write the matrix \(A\) so that \(T(\mathbf x) = A\mathbf x\text{.}\) Then verify that \(T\left(\twovec{x}{y}\right)\) agrees with what you found in part b.
In this section, we will demonstrate how matrix transformations provide a convenient way to describe geometric operations, such as rotations, reflections, and scalings. We will then explore how matrix transformations are used in computer animation.
Matrices can be used to compactly write and work with multiple linear equations, referred to as a system of linear equations, simultaneously. Matrices and matrix multiplication reveal their essential features when related to linear transformations, also known as linear maps.

Solving a system of equations can be a tedious operation where a simple mistake can wreak havoc on finding the solution. An alternative method which uses the basic procedures of elimination but with notation that is simpler is available. The method involves using a matrix. A matrix is a rectangular array of numbers arranged in rows and columns.
