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.

IA=AI=A the order doesn't matter in case of identity matrices
Thanks!
that's the answer I got, good job!
as long as the dimensions are the same
thank you. you are helping me to learn a lot in mathematics
In identity matrices the order don't matter, I've tried on my notebook
this is better than paid udemy courses.
loved it just need for my igcse exam tnx sooo much XD
how did ur results came out , u must have already finished A levels
this video is so helpful
Isn’t o*4 and 0*7= 0??
very good video, I like
AI equals A
SUNSHINERose78 yes
Sir ji in place of A if there is a no 3,if we multiply it by identity matrices can it equal to 3
For some reason it was very hard for my brain to do it I x A, but I think I finally found the answer and it's very interesting. (assuming I did everything right) thanks.
You're definitely not to blame,
it's just your gender, it has a tendency to make basic mathematical expressions seem like gruelingly complicated sights to behold. But luckily that's a syndrome nearly half of the population suffers from, so there is no reason to feel any less over it.
Here, I hope I managed to put your mind to rest. I shall not even ask for any kind of compensation, because that's the kind of ever-giving and stunning selfless guy I am. You're welcome.
LOL. Thanks. I really needed a good laugh today.
The Tyrannical Mangineer Why so sexist
Avarice im a girl and i like math
@@CTheNice is this a joke
thank u
Nice
No matrix -- can accept any - odd num - lttr!
Yes.
Is it possible to have an identity matrix which is a (1*1) matrix?
Pius Darko [1]
isn't that just a scalar?
;
IA != A ??
+Бојан Драшко AI = IA = A
Hot
we will have (A) INVERSE
do you really have to repeat everything 6 times omg, cant even watch this bc of that
This video was made 10 years ago, people had proper attention spans back then
@@advaymayank1410 yah old grandpas probably who love wasting time as much as this guy. i found a better video who taught me everything 10x faster.
i wont stand for any khan academy slander
