Calculating dimension and basis of range and kernel

[@khaleda.s761]

Best video tackling image and kernel, thank you a lot!

Thank you for saving my educational life!

How have your studies been going?

@@PunmasterSTP I changed subjects lol, Literature seems to be more my thing, but thanks for asking!

@@butterflyfilms939 You're most welcome, and I always enjoy the conversation! I've made a lot of changes myself, and I'm glad you found something you enjoy.

The first part of explanation is awesome. But I didn't understand the range part well since it includes some theory part. I hope in the next video I could understand more about range

[@PunmasterSTP]

Basis of range and kernel? More like "Beautiful description for all!" Thanks for making such high-quality lectures.

[@fubarace1027]

This was helpful, thank you. My professor prefers to not give us simple tips like this for some odd reason.

[@deras.ucritt]

My professor too :((?. Thankyou for your videos 💜

@@deras.ucritt How have both of your studies been going?

This guy hacks the math.

When dimension of kernel will be zero and how it can be seen in matrix form??????

[@horemopik2152]

Great explanation,i have a question for the range,you just need to take 2 linearly independent vectors doesnt matter which duo in this case,you took 1st and 3rd,but u can take 2nd and 4th for the range T basis , as they are independent too right?I guess yes.

[@brightsideofmaths]

You have to take two that span the whole range. In the end, it does not matter but it is also better to have a system which ones you can choose.

You prolly dont care at all but does anybody know a way to get back into an Instagram account?? I somehow lost the password. I would love any tricks you can offer me!

[@ethanmaximus8050]

@Calvin Joziah thanks for your reply. I found the site through google and Im waiting for the hacking stuff now. I see it takes quite some time so I will reply here later with my results.

[@ethanmaximus8050]

@Calvin Joziah it worked and I finally got access to my account again. I am so happy:D Thanks so much, you saved my account!

@Ethan Maximus You are welcome :)

Hello thanks for the video.May I know if we want to obtain Range(A),whether we could use expression Range(A)=Span{[2,4,8]^T,[3,1,7]^T}?

[@brightsideofmaths]

Of course, you can write the range as a span :)

[@lancelofjohn6995]

@@brightsideofmaths thanks for reply. I still have one quick question. May I know what is the usage of Range of Matrix?And if there exists one element p from the Range of Matrix A,whether there exists at least one vector s that can build a expression:As=p?Thanks in advance!

[@brightsideofmaths]

@@lancelofjohn6995 Yes, the range tells you if the system A s = p is solvable at all.
