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.
For free. For everyone. Forever. #YouCanLearnAnything

Thank God. A simple concept. Maybe i can get at least a 5% on my test now
Hah hah hah hah
haha same.
Haha
I was doing maths with a moody face but you made me smile😂😂
@@kencasper4961 lol I have no memory of commenting this. Glad it made your math experience less painful
This man is the reason I will pass both my math classes in University
Thats nice. Whats your point?
I study in university
give it to the man, hes smart ok. no need for pride. good on ya imerence
Same
sup dude how you doin after 8 years?
You know when scientists are bored, they dont play COD or hang out with buddies like us, they make stuff like matrix transpose.
Idk how they have the energy to do so tho like why waste so much time creating stuff like this just to make ppl loose braincells
@@rubabnaqvi7285 its literally just turning it by 90° ?
@@Murv brother you did not understand the video haha
@@wilmer4421 Huh ? But it is just transposing it by 90 degrees
the rows rows become become the columns columns
I don't fully get it but I like it
I forgot everything we did on undergraduate haha I feel so stupid. At the graduate level, we are expected to know everything to be able to do stuff do now. So this channel really helps me revisit and remember what I have learned and forgot. 1 class is econometrics and matrix algebra is a very important part of it and I have been watching it for the past hour. Good luck everybody on exams
i can relate about forgetting what ive learnt lmao
They are usefull in game programming for example ;) OpenGL uses matrixes a lot.
really?
@@kklol07 Matrix multiplication is exactly why you can have perspective in game graphics.
I am actually looking for a video on why we do this, not how to do it. Do you also have a video on that?
Im guessing he has videos of it on the linear algebra playlist
I can give you a practical application (if not a mathematical one).
I had to export matrix elements from one piece of software to another, and each piece of software was interpreting matrices in the opposite way. One was the transposed version of the other.
I had to use a 'transpose' python method to rectify the mis-match. Apparently the choice of row, column or column, row is largely arbitrary in software design.
@@rootytuners That would be the inverse (which is the transpose for orthogonal matrices).
@@wellwhatevr22 ... why would it be the inverse
Glad you posted these. I will be taking Quantum Mechanics next year and my professor said that I can get by with just Calculus 3 and not linear algebra. These will help out alot during my study sessions :).
WOW QUANTUM MECHANICS? wow sounds like something ive only seen in young sheldon haha...man it must be hard af
Good luck
I've never understood or really knew anything about the matrix other than Neo. Now I actually see the matrix thank you
As you probably know, you can write a linear map between vector spaces as a matrix. The transposed matrix then represents the so called 'adjoint linear map'. This may be used to find a diagonalization of this matrix.
Also you can use the transpose to decide whether the eigenvalues of some matrix are real or imaginary. Wikipedia -> Keyword: Symmetric and antisymmetric matrices.
If you want to do graphical programming (for games), you'll need to know about matrix transposing. I'm not sure what it's exactly used for though.
someone said its used in openGL (??))
Thank you so much sir! I can undoubtedly say that even today we have no channel other than yours who can teach all the concepts so deep and easilyyy...u don't even know what u r giving to us....thank you thank you sir sir....from wholeee of myyy heart........I don't know why is this channel so underrated in India...perhaps bcz whenever we search a topic on youtube videos from your channel don't even appear on screen...you should maybee work on your titles or something....I can just thank godd that I found your channel sir.....LOTSSSS OFF LOVEE FROM INDIA
his channel and the chem tutor channel are amazing they both explain clearly. i recommend that channel to you for maths and chem related stuff!
My linear algebra prof took 15 minutes to explain this and then ended up confusing me. Thank you for explaining simply in 3 minutes.
One simply example would be to flip the coordinate system of a graph so x becomes y and vice versa.
Oh, wow..Really...greatman...thx
Thanks !! You're the best!
you use it to find the adjoint of a matrix, used for finding the inverse i believe. which in turn is used for solving systems of linear equations, algebraic and differential
Tell me, what for i will need these matrix Transpose?
this thing you learned 10 years ago finally prove itself useful?
This vid is such a mood
Thanks To God , he helped me through this channel 🎉God bless you and your family sir😊Thank You
Why is transpose of a matrix needed?
Wait until you enter FUTO
I love this guy
I guarantee you that deep within the source code of COD is a function called TransposeMatrix or something very similar.
yes my main man, Sal strikes again.
Are you Tom Hanks ?
😂😂😂😂😂😂😂😂😂😂
r/emojipolice You are under arrest for using > 4 emojis
Thank you
Thankyou so much!
Sir how we mathematical define transpose of a matrix?
Or is this only way row becomes column and columns becomes rows.
Thank you 100%
Thanks
Thanks man
Thank you so much!!!
Perfect easy
thanks a lot
Thanksss😭
Awesome! ty
Thanks😉
thank you sir
Excellent
U r great
It was osama
so while transposing a Matrix, a11 will be always constant?
When you find the transpose, you switch the indices. 2-1 becomes 1-2.
N-M becomes M-N. If the indices are equal then their position doesn't change
Nice
Grazie!!
Actually I'm a bit surprised that no one talked about his voice
thaank you ...sir
❤
I forgot what the T meant so when I took my quiz I had no clue what to do and left it blank. Who knew it was so easy.
What is transposing of matrices??
All the raws become columns
All the columns become raws
Just simple as that.....
sounds like frank zappa is teaching maths
correct XD
can anyone tell me what software he is using and tools/devices?
I want to make my own tutorial...
Thanks a bunch guys..

Hey, this may be a bit late but here's a resource I found. It looks like what you might be interested in.
Vijval Rajan Thank you

Sir how to calculate inverse of 5*2 matrices
As with ALL maths, I want to ask... .BUT WHY?
this isn't when you ask "why?", but "for what?"
no such thing as have or not
Who’s here for there gcses
( : just flip the matrix.
You spelled columns wrong the first time you wrote it.
who cares
You wrote "colums" by mistake.
It can be written as Colum and Column. It depends on the type of English.
dictionary.cambridge.org/spellcheck/british-grammar/?q=colum no it doesn't.
Colour ✔ 🇬🇧, Color ✔ 🇺🇸
Column 🇬🇧, Column 🇺🇸
who cares
@@wrestlingscience you cared to reply to a 5 year old comment
I just want to know why me a high school student have to learn that! This sooo boring, I want to make biology! Why tho....😶
Sorry man.....i dont get any Words from u.....
Now i am more confused than before..........
schlecht
Cx
holy shit you teach slow!
Slow and steady wins the race, trust me, this guy is the reason I should pass my test tomorrow!
He makes sure everyone understands his teachings, not only fast paced people. Not everyone has strong history of matrices... LOL by the way my lecturer takes 60 minutes to teach what he teaches in 10 minutes.
it's a basic teaching principle I suppose. My chemistry's teacher said the other day that, a good teacher would always teach at the pace of the slowest student.
chemistry*
This guy is nearly unbearable
thank you
Thanks lot.
