Thanks for saving me once again Prof. Dave! If you ever add to this series can you cover the following: Symmetric bilinear forms, sesquilinear forms, adjoint/ self-adjoint linear maps, the spectral theorem, Jordan Canonical Form, and positive self-adjoint linear maps.
In the comprehension question no.1 in the 1st row 2nd column it was written 2+1 but in the answer you have written it in the form of conjugate transpose 2-i
Thank you for this, a layman curious about the world, been looking at treatments of this for years, but founds some pearls of wisdom in this video that I didn't know or realize. I suppose they should have occurred to me by now, but your explanations were simple and intuitive and I feel like I gained meaningful insights. Thanks again, looking forward to more of this.
Doubt :: i need to find adjoint of Matrix , matrix comprises of Complex elements so What i have to do ? I mean I just have to transpose the matrix or to take its conjugate transpose?
"Change the sign of each imaginary number on the matrix and turn the rows into columns." vs " Show the Transpose of the Complex Conjugate of the given Matrix." Good teachers vs sadistic teachers.
Hi. I don't know more things about matrix multiplication. But I have a doubt . Why we are taking conjugate transpose instead of transpose for complex matrix multiplication ? What will happen if we don't take conjugate .
Professor Dave, I have a topic in my linear algebra and matrix paper called 'Nature of characteristic roots in case of special matrix' . Could you please post on that topic?
If i = sqrt(-1) then -1 = i * i = sqrt(-1) * sqrt(-1) = sqrt( (-1) * (-1) ) = sqrt(1) = 1. That's why I would rather assume i ^ 2 = -1, rather than i = sqrt(-1) because it doesn't lead to such contradictions.
Professor Dave Explains I get that... I just don't understand how other people won't watch. It's such a tiny percentage compared to the people that receive your videos in their subscription box.
@@ProfessorDaveExplains I'm not sure. Why would a channel with almost half a million subs only have 132 patrons on their Patreon? I know of people with 100k subs that have over 1000+ patreons. Your channel subscribers compared to the amount of people that watch just doesn't add up. I'd assume people would still click on the videos, unless it's just all botted subs. But what do I know?
Wikipedia: In mathematics, a Hermitian matrix is a complex square matrix that is equal to its own conjugate transpose. Is this really what you're saying around 5 minutes?

Whoops! In the checking comprehension for question 1, the top right entry on that matrix should be 2 + i, not 2 + 1. Sorry!
sure, thanks for the Video.
May you put more Math videos related to quantum physics.!
Thank you...but I recognize that from the solution.
It is not square matrix
Amazing Playlist ❤

He knows a lot about all kinds of stuff! Professor Dave Explains~~~

I think it's typing mistake it was 1+i
2+i
2nd week of engineering major and I need to recall this. Thank you so much!
explained in very simple and lucid style. thank for the video

Thx for saving my life, prof.
This is one of the channels that you just see one video and you instantly subscribe 😊
I needed linear algebra for better understanding the data science algorithms. Thanks for the well-structured and clear course!
Really liking these math videos. You should do a series on modern algebra as well.
4:56 the linear algebra Jesus confirmed
Professor Dave it was really pakka, crystal clear
That was the best explanation I've heard. Thanks. I really appreciated your video where you discussed who you are.
Thank you so much for the amazing series
I have learned many things from it
This lecture is bloody good.. Thank Prof.
U gotta way to make things lucid, thank you sm ❤
Amazing lecturer. THanks Professor !!

This guy does better than my prof
This was really well explained! Thanks! I (along with countless others) appreciate this!
Could you solve the problems?

It's not identity Matrix tho

Thank you very much for the Korean subtitles!!
Thats great thank you so much ❤ from Jordan 🇯🇴
Excellent, thank you!!
Thanks bro
Thanks a lot Professor Dave💞💞💞💞💞
Crystal clear. Love it!
thank youuu sir
Hello , what is the identity matrix in C ?
Hey how is the conjugate of that original matrix in the first example not -7 but remains as seven but all the other terms have their signs flipped?
شكرا ً جزيلاً
Thanks a lot
Thank you sir ...... it's more helpful for me .... thanks a lot
The first entry in column two is 2+i but not 2+1
Thanks, man! Your video is great.
Thanks very very much Professor. You have really thought me a lot. I’m much grateful. God bless you as well 🙏
This video is amazing! 👍🏻
What does orthonormal basis mean?
Thanks sir very clear
Second...🙋very usefull video...thank you sir...
What is the value of (i) in unitary
Thanks a lot for your efforts.
This video helped me a lot.
Lots of love,hope and trust from Indian occupied Kashmir.😍
You are amazing. PLZZZZZZZ keep up the good work up.
Let’s assume it’s right the way it was given and agree to it being a Hermitian Matrix🙂
Could you make a video about cramer's rule
i did that already
@@ProfessorDaveExplains oh really? I didn't notice that😂
check out my mathematics playlist, it's got everything you need

allah anlatsa ancak bu kadar güzel anlatırdı.

8:15 type on the original matrix. should be 2+i in upper right corner
whoopsie! thanks for catching that, i'll pin a comment.
thank you for your videos dave! Keep it Up!!
Excellent 👌🏻
If i = sqrt(-1) then -1 = i * i = sqrt(-1) * sqrt(-1) = sqrt( (-1) * (-1) ) = sqrt(1) = 1. That's why I would rather assume i ^ 2 = -1, rather than i = sqrt(-1) because it doesn't lead to such contradictions.
It's not a contradiction. You just said that i^2 = -1, and -i^2 = 1. That's how negative numbers work.
Yes. it is 2+ i. But anyway. Great video. Thank you Professor Dave. Will there be more videos of Linear Algebra??
thank you...university of Baghdad
nice one
Time to go to advance mathematics woohoooooooooooooooo
Easy
Can anyone check q3 in exercise?

What's up with your video view to subscriber ratio?
The only people that are dying to watch a linear algebra tutorial are people who are currently studying linear algebra.
Professor Dave Explains I get that... I just don't understand how other people won't watch. It's such a tiny percentage compared to the people that receive your videos in their subscription box.
Why would they watch if they aren't studying linear algebra? My content is not at all entertaining.

@Abhay Kamath bad idea
Wikipedia: In mathematics, a Hermitian matrix is a complex square matrix that is equal to its own conjugate transpose.
Is this really what you're saying around 5 minutes?
Ah "hermitian transpose" not the same as "hermitian matrix"
