Matrices as transformations
Learn how matrices can be used as transformations of vectors or transformations of the plane.
Sal transforms a 2-dimensional vector using a 2x2 matrix, and draws the original vector and its image on the plane.
Find the result (both algebraically and graphically) of transforming a vector using a transformation matrix.
Sal transforms a triangle using a 2x2 matrix.
Find the image of a given polygon under a transformation defined by a given matrix.
Learn how exactly 2x2 matrices act as transformations of the plane.
Learn how to determine the transformation matrix that has a given effect that is described visually.
