Transforming vectors with matrices

In this lesson, we will learn how to transform column vectors with matrices. To transform a vector, we need to multiply the transformation matrix with that vector. This would result in a transformed vector, where the length or direction of the vector may be changed. We will take a look at some questions which involve transforming vectors, and then graph them to notice the changes between the normal vector and the transformed vector.


Let column vector x be a column vector and TT be a transformation matrix. Then we can transform the column vector column vector x by multiplying it with the transformation matrix TT. In other words, transformed vector Tx is the transformed vector.
