Webyou want to be able to reach any (every) point in R^n, and those can be reached by a combination of at least "n" number of basis vectors, you need to have at least that many basis vectors in your matrix to have the "onto" condition if you have too few basis vectors (can't reach every point of R^n), then the "onto" condition does not apply WebMar 5, 2024 · To show that T is injective, suppose that u, v ∈ V are such that T u = T v. Apply the inverse T − 1 of T to obtain T − 1 T u = T − 1 T v so that u = v. Hence T is injective. To …

WebThis is only true if the codomain has the same dimension as the domain. For instance, obviously there are linear maps that are injections and aren't surjections from k to k 2. I'm pretty sure the definition is just using the notation B = F [A] to indicate that the map is surjective. Continue this thread WebThe easiest way to determine if the linear map with standard matrix A is injective is to see if RREF ( A) has a pivot in each column. The easiest way to determine if the linear map with standard matrix A is surjective is to see if RREF ( A) has a pivot in each row. 🔗 Activity 3.4.18.
WebIn general, to show that a linear map $T$ is injective we must assume that $T(u) = T(v)$ and then show this assumption implies that $u = v$. Though, there is another way… The …
