  1. linear algebra - if $T: V\to V$ and $ dim (KerT)+dim (ImT)=dimV $ can i ...

    Mar 29, 2023 · $KerT+ImT=dimV$ ? Is this possible? $Ker T, Im T$ are subspaces of $V$ and $dimV$ is a just a...

  2. Finding the basis of ker (T) and im (T) - Mathematics Stack Exchange

    Jul 19, 2021 · For the most part, you're correct. Part (a) is fairly straightforward; B:= {1, x,x2} B:= {1, x, x 2} is the standard basis we use for this space after all. You should probably verify that it is, indeed, a …

  3. Show that $ImT^t= (kerT)°$ - Mathematics Stack Exchange

    Mar 1, 2015 · Let $T:V→W$ be linear transformation and V have a finite dimension. Show that $ImT^t=(kerT)°$ I have to prove it by mutual inclusion. I have proven the first ...

  4. linear algebra - Prove Ker$T= ($Im$T^*)^\bot$ and (Ker$T^*$)$^\bot ...

    May 26, 2023 · This means we have $v \in (ImT^*)^\bot$ and therfore we have $KerT \subseteq (ImT^*)^\bot$. For the other side, consider $0 \neq v \in (ImT^*)^\bot$, (which exists from the same …

    Jun 15, 2019 · Find a basis for KerT and ImT (T is a linear transformation) Ask Question Asked 6 years, 8 months ago Modified 6 years, 8 months ago

  6. SageMath: Orthogonal projection of $\mathbb {C}^3$ onto a subspace.

    Dec 13, 2024 · Now, my problem arises when I evaluate P_imT with specific values of a,b,c (in this case, the standard basis of $\mathbb {C}^3$) in order to obtain the columns of the projection matrix …

  7. Prove that $T^*$ is injective iff $ImT$ Is dense

    Dec 21, 2014 · The title of your question does not really match the actual question (maybe the statement of the current question is used to prove the result in the title?). Is this intended?

  8. linear algebra - $S∘T=0$ if and only if Im$T \subset$ ker$S ...

    Dec 5, 2013 · Let $T:\mathbb {R}^n \to \mathbb {R}^m$ and $S:\mathbb {R}^m \to \mathbb {R}^l$ be linear maps. I have to show that: $S∘T=0$ if and only if Im$T \subset$ ker$S$ Can ...

  10. Oscillatory integral giving me the willies - Mathematics Stack Exchange

    The prefactors p r e f a c t o r s can only be determined from the 'exact evaluation' ( see the @Brightsun fine answer ) but the qualitative evaluation yields the correct asymptotic behaviours m−−−√ …
