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.

I was struggling to understand how to multiply matrices by some unclear explanations, this helped a lot, thank you!
Karteek Ch I have no idea what I am doing with matrices- I was never taught how to multiply them and am expected to know exactly how to do it now.

yeah cos this video is like hundreds of thousands of images and videos are more interactive than a book. Book is limited in this aspect

The way he says 'us humans' makes me wonder if he's an alien
xd
gem from 2014
This takes me back to uni, liked doing matrixes was fun
Thank you sir
Very good video, but when explaining something like this, you should never use the same numbers in the matrix. It just makes it more difficult to understand. But using different numbers everywhere makes it very easy, :)
I know math has no age but it's 2020 thank you very much
it's like crying out bankaaiiii! in the last moment.
It solved all of my math😎
Thank you
Nice!
Thanks we love you I do
Oh wow this video is 9 year ago but explain is too solid

Thank you ❤
Great
I agree with The_Pyromancer Why IS IT hard for the our school books to show how to do this and save us from going onto youtube and searching it up anyway DONT FORGET TO SUBSCRIBE TO KHAN ACADEMY BECAUSE THEY DO WHAT THE BOOK CAN'T
Because books are only meant for one kind of learner. Not everyone can learn from a book.
how do we multiply a 3*2 matrix with a 2*2 matrix?
Not it is not possible (unidentified)
@@yousraelangouri9986 isn't it? In the video he says that the columns of one and the rows of the other must be equal. The two of the columns and the two of the rows are equal.
Same thing probably, but you do an extra row at the bottom
I'm trying to find that out rn but the answer will be a 3x2 matrix
I didn't know it was possible to snip back in 2013
I finally get it
I think I should've had studied more for tomorrows exam
Magic Numbers..
FTLsFINEST Bad channel you have
I just uploaded a video about multiplying matrices, if anybody needs additional help ^^
Anyone else here who was supposed to do it in Java but wanted to understand how it worked in the first place? xD
bruh im retaking algebra 1 in high school and they got me doing precalc work?? 💀
I’m in precalc trust me this is not precalc work
No one is telling the concept why we are doing multuplication like this.
I love you
Hi
hello
By me being here at this time while also being the 68 comment but also isn't because time and space is the same thing because matrix is matrix but also isn't but is or a simulation of endless loops/ possibilities/ also and or pewdiepie in the end but also adam is also but isn't is or aman or probably a man or infinity
This man sounds like YandereDev
I am sure there is no Indian here except me..(
Why do you think so?
@@BoyzzWorldGamingyou are late
@mrbeast @pewdiepie @DanTDM @skeppy not that hard to learn matrices, is it ?
Are everyone here nerds Just curious?
Thanks
