What is an example of a linear transformation?
Example. Recall the linear map T# R2 R2 : ! which rotates vectors be an angle 0 # < 2 . We saw before that the corresponding matrix for this linear transformation is

What is the performance criterion for compositions of transformations?
10.3 Compositions of Transformations Performance Criterion: 10. (f) Find the composition of two transformations. It is likely that at some point in your past you have seen the concept of the composition of two functions; if the functions were denoted by f and g, one composition of them is the new function f◦ g.

Are linear transformations corresponding to direct function composition and matrix multiplication the same?
But this is just the k-th column of A. Hence, the image of vk under the linear transfor- mation corresponding to A2A1 is T (vk). Thus, the linear transformations corresponding to direct function composition and to matrix multiplication have the same e ects on the basis elements vk, and hence are the same linear transformations.

What is the composition of a linear map?
Given linear transformations T1 : V ! W and T2 : W ! W 0 for vector spaces V; W; W 0, their composition T = T2T1 : V ! W 0 is their composition as functions. That is, if v 2 V , then T (v) = T2(T1(v)) 2 W 0. On the homework, you showed that this composition is indeed a linear map.

1. Prove that the composition S T is a linear transformation (using the de nition!). What is its source vector space? What is its target vector space? Solution note: The source of S T is R2 and the target is also R2. The proof that S T is linear: We need to check that S T respect addition and also scalar multiplication.

S @ @ @ @ R S T As each of T and Spreserve linear combinations, so will the composition, so S T is also a linear transformation. Coordinates again.

One thing that was probably glossed over when you ﬁrst saw this concept was the fact that the range (all possible outputs) of the ﬁrst function to act must fall within the domain (allowable inputs) of the second function to act. Suppose, for example, that f(x) = √ x−4 and g(x) = x2.

examples of linear transformations. Since linear transformations are just functions from a set of vectors V to a set of vectors W, in the right circumstances we can get a new function from two old ones just by taking composition of functions. De nition. Given linear transformations T 1: V !W and T 2: W !W0for vector spaces V;W;W0, their ...

Examples: State the coordinates of the point after the indicated composition. 1. − ∘ 2,−3(4,2) 2. −2,5 ∘ ,90°(4,2) 3. Find the image of A(4, 2) after the following transformations a. 1,4 ∘ − (4,2) b. − ∘ 1,4(4,2) c. Are the two transformations from parts a and b equivalent ( does 1,4 ∘ − = − ∘ 1,4 )?
