Introduction to Eigenvalues and Eigenvectors – Part 1: Definition and Quick Example

In this video, I introduce the concept of eigenvalues and eigenvectors, explaining their definitions clearly. We walk through a specific example showing that a given vector is indeed an eigenvector of a matrix 𝐴 corresponding to the eigenvalue 𝜆 = 4.

Finally, I provide a quick proof demonstrating that if a vector is an eigenvector, then any multiple of that vector is also an eigenvector.

What’s covered:

Definition of eigenvalues and eigenvectors.

Example: Proving a given vector is an eigenvector for matrix 𝐴 with eigenvalue 𝜆 = 4.

Proof: Showing that any scalar multiple of an eigenvector is also an eigenvector.

This is Part 1 of a series on eigenvalues and eigenvectors, perfect for students learning linear algebra or preparing for exams. Make sure to watch Part 2 for a deeper dive into finding eigenvalues and eigenvectors step-by-step.

Hi all! Please post comments, questions and anything else on your mind in the comment section! While I try to answer as many questions as I can, there are more questions than I can answer by myself so if you are someone who might be able to help, please do so! The community is so much better when everyone is involved and helping each other out. Our strength is our willingness to help each other!
Also please feel free to like or dislike the video. Your feedback is always appreciated so that hopefully I can make my future videos the best possible! Thanks and happy studies!

Ok, after much ado, part 2 is finally out there.  It is titled ' Finding Eigenvalues and Eigenvectors '  - please upvote this comment so that others will see it! Thanks.

This is the simplest, most clear video on eigenvectors/values and I cannot believe I've been struggling with these for so long. I'm a physics grad student and I've been muddling my way through classes trying to piece together what these are supposed to represent. Thank you Patrick.

You just explaned this to me CLEARLY in 5 minutes, that our university didn't manage in one and a half hour. Thank you very much.

I must say, I have read a couple of math books trying to really get a grasp on this concept, and you just brought up the lights man. Thanks thanks thanks.

I was so confused about what an eigenvalue and eigenvector is in the multivariate class I am taking. You helped me understand it! Thanks so much!

You sir, need more recognition for your work. May your life be as easy as the exams I did after your instructions.

The simplest way of showing eigen vector and value. As Einstein said, any complicated thing can be explained in a simpleway. You have done it. Thank you very much.

in stats, a variable with a bar usually means an average. in linear algebra / physics, it refers to a vector. much different!

Hello Patrick, just stopped by to say great channel. As an advanced math degree holder myself, I'm very interested in creating a channel where I can briefly go over theory and solve math problems like you do, and I've to say that your channel is certainly an inspiration!

For the past two week my professor has been talking about eigenvectors and eigenvalues and I have been so confused out of my mind. Now I understand.
