This concept is explored in this section, where the linear transformation now maps from one arbitrary vector space to another. Let \(T: V \mapsto W\) be an isomorphism where \(V\) and \(W\) are vector spaces. To prove the transformation is linear, the transformation must preserve scalar multiplication, addition, and the zero vector. S: R3 → R3 ℝ 3 → ℝ 3. First prove the transform preserves this property. S(x+y) = S(x)+S(y) S ( x + y) = S ( x) + S ( y) Set up two matrices to test the addition property is preserved for S S. Given A x⃑ = b⃑ where A = [[1 0 0] [0 1 0] [0 0 1]] (the ℝ³ identity matrix) and x⃑ = [a b c], then you can picture the identity matrix as the basis vectors î, ĵ, and k̂.When you multiply out the matrix, you get b⃑ = aî+bĵ+ck̂.So [a b c] can be thought of as just a scalar multiple of î plus a scalar multiple of ĵ plus a scalar multiple of k̂.

In practice, one is often lead to ask questions about the geometry of a transformation: a function that takes an input and produces an output. This kind of question can be answered by linear algebra if the transformation can be expressed by a matrix. Example Testing surjectivity and injectivity. Since range(T) range ( T) is a subspace of W W, one can test surjectivity by testing if the dimension of the range equals the dimension of W W provided that W W is of finite dimension.
