thus T3 /? U. So U is not closed under addition of linear maps. D. [3B5] Give an example of a linear map T : R4 ? R4 such that range T = null T.
B # 5 Give an example of a linear map T : R4 ? R4 such that range(T)=(T). Let e1
4. Find an example of a linear transformation T : R4 ? R4 so that null (T) = range (T). Example: For any
23 July 2013 mapping T : V ? W is called a linear transformation from ... Example. Determine the matrix of the linear transformation T : R4 ? R3.
2 Linear Transformations Null Spaces
a subspace U of V such that U ? null T = {0} and range T = {Tu

In other words the null space of a linear map is the collection of all of the elements in U that T maps to 0. For example

Let L: R3 ? R4 be a linear transformation. P below is such that [x]T ... x2)T. This linear transformation stretches the vectors in the subspace S[e1] ...
B # 5 Give an example of a linear map T : R4 ? R4 such that range(T)=(T) Use the fact that 5 = dim(R5) = dim(null(T)) + dim(range(T)) If
[3B5] Give an example of a linear map T : R4 ? R4 such that range T = null T Proof Define T by T(x1x2x3x4)=(x3x4 0 0) Then T ? L
a) Give an example of a linear map T : R4 ? R4 such that range T null T b) Prove that there does not exist a linear map T : R5 ? R5 such that range T-null T
Today's lecture is on the concepts of range and null space a pair of concepts related to the For example consider the linear map T : R4 ? R2 T(w x
So it cannot possibly be the kernel of a linear map ? : So Range(T) = Span{1x} (5) Find the matrix of the linear transformation T: R4 ? R4
(4) Find a linear map T : R4 ? R3 whose null space is U = {(x y z w) ? R4 x = w 2y = z} and whose range is W = {(x y z) ? R3 y = z} Solution:
Define a linear map that realises each of these possible values 6 Give an example of a linear map T : R4 ? R4 such that null(T) = range(T) Can you
a) Give an example of a vector space V and a linear operator T ? L(V ) such that T2 = T (Not T = 1 or 0 ) b) Prove that if T2 = T then V = null T ? null(T
Example 4 Let L: R3 ? R4 be a linear transformation Suppose we know that L(1 0 1) = (?1
