Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

I was having a very hard time with this but I think I finally understand now. Thank you very much sir.

[@Chaosflyex98]

More people need to watch your videos!!

[@DelphianSociety]

Thank you sir (by the way, friendly correction: I believe 'lo and behold' is correct).

[@bonclay7763]

is there a way to shove this in a casio calculator and get an answer? i just need to pass this module..

[@tis_i_sana]

XD

[@MrRobinsonsMathChannel]

What software are you using to "draw" on?

[@s0m0c]

Gracias!

[@SupremeChickenx]

UR VOICE IS AWESOME

[@asmamada209]

THANKS!!

[@bernhardriemann3821]

Why do we have to perform matrix multiplication when we can just apply transformation directly? Good vid sensei.

Also, to avoid conclusion: In a diagonal matrix, all entries outside the MAIN diagonal are 0! Of course a big enough matrix will have multiple diagonals, but only the entries in the main diagonal will be non-zero. This is probably logical for most of you, but just to be sure!

[@sundarchannel]

u are great.............

[@user-cx3cv9vq3b]

if you were discraibe axies as y=j aand x=i woud be less confusing

[@s0m0c]

Thanks

[@MustNotRead]

great grid

[@ivanpa33]

you are fucking great, thank you I think you are by far one the best channels you can find in youtube, thank you

[@adithyathejas]

T(x)=Ax mxn T =>R2->R3 ???

[@vexedev]

you should get paid by youtube for these vids!!!

[@NoajmIsMyName]

Is that Algbra or cocls 1

[@ocean_man8766]

I still don't understand after this video....that just proves i'm a complete idiot 😩

[@HotPepperLala]

Wow nice grid lol

[@Judobrinez]

nope do not underrstandboyyyy

[@AbebeWondie]

😍😍😘😘😘😘
