What is Linear Algebra?

This video provides a basic outline for how we will go about studying linear algebra by attempting to answer the question: What is Linear Algebra?

Sources: The example of a linear system, as well as the terms 'row picture' and 'column picture,' are taken from Gilbert Strang's Introduction to Linear Algebra text and supplemental materials.

Pretty much sums up wikipedia: "impeccably correct but not at all helpful."

Best explanation I've heard so far.

[hfe]

This is the best explanation for what is linear algebra

[Alien_at_Large]

I am legally blind and have 9 days to review Linear Algebra. Thank you for (so far, at least) making your videos "visually accessible"!

[GaryTugan]

excellent vid! thanks. been brushing up on my linear algebra after having studied it many years ago, and I don't recall any teacher ever putting these two concepts together like you did in this vid. Helped a LOT.

6:27, how the graph of vectors was drawn.?
2, -1 is clear. But

From where did you got the other two points

[alpena]

You should stretch in this video that when solving the problem in terms of vectors that the coordinate system of the graph is NOT X and Y. X and Y are the lengths of the vectors. The graphs axes should be deliberately changed to i and j. I spent a lot of ti e realizing that in the vector model the x and y axes cannot carry the x and y labels.

4:45 - I don't know anything about Linear Algebra, all of a sudden you are talking about vectors?? Talk about a shitload of handwaving! I can't follow anything after 4:45 - that's where the linear algebra starts! What is Linear Algebra? I still have no clue!

Meh, came to find out what linear algebra is. Now I need to find out what linear equations are. I assume these are equations drawn in a line.

I am freshman in college and I am taking a linear algebra course right now. I believe it is the hardest math class I have taken so far and I feel like gaining a better conceptual understanding of the subject will help me grasp the material better.

[vactum]

wow! best explanation I have heard till now, it could be very very beneficial if u made complete series on "Linear Algebra"

[federalbureauofinvestigati]

What are vectors?
both direction and magnitude OH YEAH!

[firstnamenonapplicable]

I'm basically stuck where I have to take Linear Algebra just before Calc 3, this is my life for 4 months in the spring

[waynelast]

I am trying to find a high-level overview of what is Linear Algebra for someone with good math knowledge up to advanced calculus and physics. Either explanations are way to simplistic or way too detailed.

[Aurnox]

Sir! Can we have more courses on Linear Algebra and Random processes?

[avbhinaya]

Even my utterly dumb head sees something in your videos. You're are great.

[jahongfintech]

come here to refresh me before starting my CS master's degree. This is so good. Thanks

[parthibanparthiban]

Linear algebra full concept depth knowledge is wanted sir please help me

[d.s.nadiunadiu]

How you plot those points I'm linear combination of Column vectors

[dijonstreak]

..thank YOU vanished the cloud of Linear Algebra for good !!
