Contains explanations and examples of homogeneous transformation matrices.

Explains how simple polygons translate into matrices and how to use 2x2 matrices to represent transformations in a plane. Includes video demonstrating an example where a vector must be rotated 90 degrees using matrices. [4:18]

Match transformation matrices with a visual representation of their effect on the plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Find the image of a given polygon under a transformation defined by a given matrix. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] Provides resources for working with 2 x 2 matrices as transformations of the plane, and interpreting the absolute value of the determinant in terms of area.

Students can use a graphing calculator to explore transformations with matrices. They will analyze how each element of the matrix affects the position of the image.

[Free Registration/Login Required] This is a lesson on transforming, rotating and dilating matrices.

Find the result (both algebraically and graphically) of transforming a vector using a transformation matrix. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Examples, solutions, videos, and lessons to help students learn how to multiply a vector (regarded as a matrix with one column) by a matrix of suitable dimensions to produce another vector. Work with matrices as transformations of...

This interactive applet allows you to manipulate polygons using matrices.

Math World offers the transformational matrix that allows us to rotate a two dimensional coordinate which in turn rotates the image. The page also offers the transformational matrix for rotation in three dimensions.

College-level course highlighting the biology of cells of higher organisms. Course topics include cellular membranes and organelles; cell growth and oncogenic transformation; transport, receptors, and cell signaling; the cytoskeleton,...

Come to this site to find the transformational matrix to find the vector rotated 90 degrees from the original. The site also states the special relationship between two perpendicular vectors when using the dot product.

Dozens of statistical terms are defined and illustrated in this glossary.
