We can find a basis for 's range space first by finding a basis for the column space of its reduced row echelon form. Using a calculator or row reduction, we obtain for the reduced row echelon form. The fourth column in this matrix can be seen by inspection to be a linear combination of the other three columns, so it is not included in our basis.

This example also shows that that linear regression is not always the right model choice (although, in many cases, a simple transformation of the predictors or the dependent variable can resolve this problem, making the linear regression paradigm still relevant). Task 1 is divided into two subtasks, Task 1a and Task 1b.

And a linear transformation, by definition, is a transformation-- which we know is just a function. We could say it's from the set rn to rm -- It might be obvious in the next video why I'm being a little bit particular about that, although they are just arbitrary letters -- where the following two things have to be true.

So multiplication on the left by the 2 2 matrix A is a function sending the set of 2 1 column vectors to itself - or, if we wish, we can think of it as a function from the set of vectors in R2 to itself.

When this rigid body is displaced, the point p gets displaced into a new point, which we will call g(p). A displacement is essentially a transformation of points. And of course, there are infinite points in a rigid body. If you have a second point, q, the same displacement will take q and move it into a new point, g(q).

Such a matrix can be found for any linear transformation T from \(R^n\) to \(R^m\), for fixed value of n and m, and is unique to the transformation. In this lesson, we will focus on how exactly to find that matrix A, called the standard matrix for the transformation. So rotation definitely is a linear transformation, at least the way I've shown you. Now let's actually construct a mathematical definition for it. Let's actually construct a matrix that will perform the transformation. So I'm saying that my rotation transformation from R2 to R2 of some vector x can be defined as some 2 by 2 matrix.
