Linear transformation examples.
Similarly, the fact that the differentiation map D of example 5 is linear follows from standard properties of derivatives: you know, for example, that for any two functions (not just polynomials) f and g we have d d x (f + g) = d f d x + d g d x, which shows that D satisfies the second part of the linearity definition.
A linear transformation T : Rn!Rm may be uniquely represented as a matrix-vector product T(x) = Ax for the m n matrix A whose columns are the images of the standard basis (e 1;:::;e n) of Rn by the transformation T. Speci cally, the ith column of A is the vector T(e i) 2Rm and T(x) = Ax = fl T(e 1) T(e 2) ::: T(e n) Š x:Linear Transformation Example Suppose that V = R4 and W = R3.

In linear algebra, vectors are taken while forming linear functions. Some of the examples of the kinds of vectors that can be rephrased in terms of the function of vectors.8 years ago. Given the equation T (x) = Ax, Im (T) is the set of all possible outputs. Im (A) isn't the correct notation and shouldn't be used. You can find the image of any function even if it's not a linear map, but you don't find the image of the matrix in a linear transformation. 4 comments.

So if a transformation maps vectors from the subset A to the subset B, such that if ‘a’ is a vector in A, the transformation will map it to a vector ‘b’ in B, then we can write that transformation as T: A—> B, or as T (a)=b.
