Things in R^2 are of the form (a, b), with two components while things in R^3 are of the form (a, b, c) with three components. Members of R^2 are not members of R^3 so R^2 is not a subset of R^3.

A subset of R3 is a subspace if it is closed under addition and scalar multiplication. Besides, a subspace must not be empty. The set S1 is the union of three planes x = 0, y = 0, and z = 0.

A subspace is called a proper subspace if it's not the entire space, so R2 is the only subspace of R2 which is not a proper subspace.

Theorem. R2 is not a subspace of C2.

In other words, to test if a set is a subspace of a Vector Space, you only need to check if it closed under addition and scalar multiplication. Easy! ex. Test whether or not the plane 2x + 4y + 3z = 0 is a subspace of R3.

The vector space R2 is represented by the usual xy plane. Each vector v in R2 has two components. The word “space” asks us to think of all those vectors—the whole plane. Each vector gives the x and y coordinates of a point in the plane : v D .

Theorem. (a) The subspaces of R2 are 10l, lines through origin, R2. (b) The subspaces of R3 are 10l, lines through origin, planes through origin, R3.

If you did not yet know that subspaces of R3 include: the origin (0-dimensional), all lines passing through the origin (1-dimensional), all planes passing through the origin (2-dimensional), and the space itself (3-dimensional), you can still verify that (a) and (c) are subspaces using the Subspace Test.

R2=C naturally as a set (ignoring any structure). R2 is naturally a real-vector space, but C is a field, so they are different type of objects and talking about them being isomorphic does not make sense.

The first definition of Reals still holds, we define C in terms of R, and then we observe that R is the subset of C where the second coordinate is zero.

Let be the coordinates of a vector Then. Define a matrix by Then the coordinates of the vector with respect to the ordered basis is. The matrix is called the matrix of the linear transformation with respect to the ordered bases and and is denoted by. We thus have the following theorem.

It is simple enough to identify whether or not a given function f(x) is a linear transformation. Just look at each term of each component of f(x). If each of these terms is a number times one of the components of x, then f is a linear transformation.

V = R3. The plane z = 0 is a subspace of R3.

A space in which vectors are closed under addition and scalar multiplication (added vectors and vectors multiplied by scalars are in the space or collection) is a vector space. Then R3 is obviously a vector space.

No the real numbers are not a subset of R2. In some contexts it may be useful to identify the real number x with, for example, the couple (x,0).

Yes, they are a subset, unless you are really pedantic about it. There are different definitions of C, one of which is just R^2 with a certain way of multiply stuff. In that definition, it's not exactly R, it's the set of guys that look like (x, 0), which is the same thing as R for all practical purposes.

V = R2. The line x − y = 0 is a subspace of R2.

How to Show that the Only Subspaces of R2 are the zero subspace, R2 itself, and the lines through the origin. I'm having trouble with a question from an introductory Linear Algebra book.

Theorem. (a) The subspaces of R2 are 10l, lines through origin, R2. (b) The subspaces of R3 are 10l, lines through origin, planes through origin, R3.

The vector space R2 is represented by the usual xy plane. Each vector v in R2 has two components. Each vector gives the x and y coordinates of a point in the plane : v D . x,y/.

Since it takes two real numbers to specify a point in the plane, the collection of ordered pairs (or the plane) is called 2‐space, denoted R 2 (“R two”). Figure 1. R 2 is given an algebraic structure by defining two operations on its points. These operations are addition and scalar multiplication.

C and R×R are exactly the same until you start saying you want to do things like multiply elements together.

Yes,it is possible. Consider the linear transformation T which sends (x,y) (in R2) to (x,y,0)(in R3). It is a linear transformation you can easily check because it is closed under addition and scalar multiplication.
