As a student studying in German and having a maths exam next week, and therefore watch maths videos a lot here, I no joke did not understand the title for 2 minutes straight. Why Eigen but vectors instead of Vektoren? A nice surprise for me surely
Mr Newton-you have just delivered an excellent exposition on a very important topic on Linear Algebra.Salute to you for your humble and yet professional delivery. Regards Dr.Sabapathy (Mathematician Singapore 🇸🇬)
One of the most important concepts, encountered super frequently in so many branches of maths/stats/economics and even AI nowadays. Thank you for explaining Eigenvectors so nicely!
Penso che questo professore sia uno dei migliori che abbia mai visto in tutta la mia carriera scolastica. Dopo tanti anni ho voluto iniziare di nuovo a studiare matematica e fisica perché dopo l'università non ho avuto occasione di applicarla nel mio lavoro. E' un vero piacere seguire le lezioni di questo signore!!!!!
Iam impressed by how effective and efficient the presentation of your online video lecture is ,am following you here in East Africa at South Sudan Juba
Awesome. Your joy of teaching jumps from the screen, it's almost palpable. May I suggest a video class on the _geometrical_ interpretation of the eigenvalues and eigenvectors. I would love to see your take on this topic.
A German once said to me that only German speakers and Dutch (me) speakers can have a really true understanding of what an eigenvalue or an eigenvector is. And yes, I have spelled them correctly because in Dutch a noun is not spelled with an initial capital, in contrast to German.
Great video Mr Newton. You explained this concept so fluently- something I could never assimilate from text books. I know that this idea is applied in Quantum Mechanics. May be next video you can give some actual applications of the EVs. Have a great day. You are wonderful 👍
There's an easy way to calculate Eigen Characteristic Equation of a 2x2 Determinant The coefficient of x is the trace of the determinant (Sum of the Top Left and Bottom Right elements). And the constant term in the equation is the Determinant value of the Matrix.
Computing eigenvalues & eigenvectors shows-up ad nauseum in Math, Physics, Engineering, etc. A powerful application of Linear Algebra is in Differential Equations, where the concepts of eigenvalues, eigenvectors, orthogonality, inner product, etc. are used to construct solutions.
... Good day to you Newton, I need to add that " Eigen " is not only a German word, but also a Dutch word (lol), and now I'm continuing your presentation regarding LinAlg ... take care friend, Jan-W
@@utuberaj60 Good day to you sir, " Eigen " in Dutch means let's say " from me "' , "' my property "' , "' my possession " , e.g. ' mijn eigen huis ' means ' my own house ' or ' een eigen karakter hebben ' means ' having a character of his/her own ' ... I hope this made it a little clear to you?! ... take care, Jan-W
Question: in a matrix like 1, -1 1, 0 If I try to get the eigenvalues I end up with L^2 - L + 1 = 0 And now L must be complex. Do the eigenvalues and eigenvectors still exist as complex numbers, or do they not exist at all?
So according to QuantumMechanics we live in a Determinant Universe? :-) I like your style of presentation. I do have a problem with determinant's however. To me they are just algebraic entities that are used to help work things out. But what are they? What is their reality in the Physical World? We use matrices to represent things, like Dirac did say, but what did the determinat of a matric mean in that conceptual bundle? I can agree that their use algebra is consistent and that adjuncts are only a little more blind numbingly dumb. I tend to see eigenvectors as a prefered direction and the eigenvalues are just their scalar, ie an attribute. What I can't see is the 'Physical' meaning of the determinant in all this. If a matrix is representative of a physical reality then its determinant must also be, but I haven't a clue as to what. You could accept that they are just algebraic flukes but that would be to doing what folk have been doing for the last 100 years, just calculating. I suppose I am looking for an intuative view of what a determinant is. It has bugged me for a life time, your presentation has rekinled my curiosity :-)
The very moment I see your smiling face, I feel happy! You are such an wonderful and passionate teacher sir!

very nice video! you actually explain the reasons for why we do what we do and it makes all the difference for learing!!

Thank you! Glad you think so.
I wish you had been around 50 years ago. What a great explanation!
One of the most important concepts, encountered super frequently in so many branches of maths/stats/economics and even AI nowadays. Thank you for explaining Eigenvectors so nicely!
If Lamda =3, then v=[-2
1] so, this is the eigenvector 2
And quantum mechanics! 🎇
Thank you so much! I'm currently studying this same topic! And your handwriting is amazing!
Prime Newtons is our very own master teacher! Unser eigener Meister Lehrer! 🎉😊
Sir your greatness is truly appreciated Thank you warmly from Iraq❤❤
You litteraly saved me for my final exam I love you
Congratulations!
This gentleman deserves more of my tuition money than my university

It is good to see you in algebra video after the pause
This is spectacular. Thank you! Can you please go over repeated eigenvalues and their possible eigenvectors?
Just starting your mix on eigenvalue/eigenvectors and it's great. I've always struggled with these and your explanation of Av=lambdav is very helpful.
Mr. Newtons your video SAVED me. Thank you so much for the wonderful explanation sir.
Amazing videos, a full 10! Explained beautifully, clearly, best in youtube. Thanks

Just Love Sir
hi mr. newton im new to ur channel and ur vids are great and i have a doubt can u tell me how u find out the other eigenvector ?
thank you sir for save my life!
[1,-2] is an eigenvector associated with the eigenvalue of 3.
Did you check it it satisfy AV=YV ?
No right?
@@bestvideo9158 buddy it did work plz check again!
Very perfect explanation 😂👏👏👏 bravo!
Great explanation!
Glad you think so!
You are awesome!
Sir, please make a video on schrodinger's wave equation.

Thak you sir
Wea do you lecture so that I can apply there
What if my X1 is > 1, eg 2,3 etc what will be my X2
Wow
can someone explain to my why the x1 = 1 in the eigen vector ? Btw great clip!
You just choose 1. You could choose any other number as long as it's nice for you. Just avoid 0 in this case so you don't get [0 0].
@@PrimeNewtons okk thank u
2 of mat {1 0
0 1}=2 x 1=2
when multiplying 2 and matrix it will become {2 0
0 2} then it will become 4
i just need answer
S0 de eigenvectors u will de coefficient as de answer
doesn't the first eigenvector be not only [1,-1] but [any number, -any number] ?
also second eigenvalue has infinite number of solutions. Is it correct?
but of course. Eigenvector is kind of a misonmer since it is not unique. Think of it as Eigenspace that is the span of infinitely many eigenvectors...
You can record video about this
Prove that tr(A^{m}) = sum_{k=1}^{n}{λ_{k}^{m}}
in the near future
Is there a way to do that without talking about the Jordan canonical form? Or would I have to stick to diagonalizable matrices?
@@PrimeNewtons I thougth that there is easy explanation without Jordan form working for all matrices not only diagonalizable
@@holyshit922 Yeah. Maybe Shur form but there's a lot to explain. Maybe in the future.
The other eigenvector is (1,-2)
Wolfram|Alpha code:
eigenvectors | (1 | -1
2 | 4)
Ja, Deutschland ist überall.
May you guess what this languqge is😊
Eigen is a Dutch word. It means "own".
