Introduction to the matrix | Matrices | Precalculus | Khan Academy

Missed the previous lesson?

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

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.

Part 2: How matrices help you to dodge a bullet :)

[caleblee]

So, a matrix is the most compact way of representing numbers, and that's why it's used everywhere?

[TheWeepingCorpse]

This is at the heart of all 3D games, alongside Quaternions (shudders). Learn it because you'll need it.

I just started Algebra II without the knowledge of matrices (really dumb move), but this playlist helped me a lot

[judycorstjens]

what has he got against even numbers?

[MrDands]

What if I told you Khan Academy is awesome?

[benmann]

I never realized the depth of these lessons until i started following along

[angryfaic]

Holy crap the first minute of google autotranslation was almost spot on.

99% comments - matrix movie jokes
0.9% - more matrix jokes
0.1% - this matrix joke

[Genghiskaran]

i have a circuit design book from college it introduces somethin about circuits and programming or somethin idk maybe this stuff will help me understand it better i dunno

[BrandonHilde]

can you spend some time talking about computer graphics and how they are related to matrices .... I Have been programming computer graphics and doing tutorials on it but have only touched on 2 dimensions and would be interested in some 3D info.

[ItsHayley]

the movie is mind blowing but i love the math way of the matrix as well :D

[hesohit]

What the difference between a matrix and array?

[soso]

I can’t believe they put pre calculus stuff on my tests...

[thaneros]

The one is the sum of a remainder of an unbalanced equation inherent to the programming of the matrix

[OmadiEmmanuel-qxer]

Plz talk about Eugen values in matrices

[clark_cant]

Awesome video and explanation of real-life use of matrices!

[lcbreezyl]

I thought this was going explain a theory of life in "the matrix". So psyc courses do cover it

[kadencronick]

1:15 I was taught the columns and rows were switched for Matricies, does it matter since you did them the opposite way?

[addisonbarton]

I needed some help with my ALGEBRA 1 CLASS on this topic (I was absent) and I saw this and read pre calculus, I'm not supposed to take pre calc for 3 more years-
