Ok, so he mentions that "(a . b) = ||a|| ||b|| cos" can be used to find the angle between two vectors but then fails to show how. This videos are starting to suck more and more... NICE WORK SALL!!
The best thing about these videos is that you get so motivated to study. A few minutes ago, I was like "Man, I got to hurry up with these dishes, I wanna study!"
Sal gave me my A in the first math course I had a t college, and is giving me the A in the next one right now <3
@Osman9100 Hi bro....little correction but dont think me as non-muslims I am a muslim and I am from India.....one thing I can say for sure Math, science, medicine, astronomy and many other sciences were first invented by Indians in the world not by any Arabs or European even. Coming to Islam I will say the only true religion on the phase of earth as it explains us about such great mysterious of time which were not of human knowledge, and this is not by arabs this is by almight god Allah.....
sal, my linear algebra book defines the zero vector to be perpendicular to every vector. Yet you said that for a and b to be perpendicular, both of them must be non zero.

Thank you so much you helped me a lot .. and this is the Muslim's contribution to the humanity as they was since long time when they produce the numeric system which all the world using now.
Our digits (0, 1, ..., 9) are called "arabic numbers", but they have nothing to do with Islam. First, they where used by the arabic people before Muhammed, and second the arabs accually adopted them from India.
The only reason they are called arabic numbers are because the europeans first learned about them from the arabs, roughly at the time of the crusades. Before that the europeans had used the roman numbers, which are quite clumsy in mathematics.
thank you for your great comments and it seems that your history back ground is nice , but you forget that Algebra comes from GABER BEN HAYAN the Muslim scholar, Muslims in the Dark age of Europ where the one who create most of the fundamental of the since that its between your hand now, so would you please try to be fear with your judgment.
I am quite aware of several mathematicians who where Muslims. They produced several great contributions to mathematics. My point was simply that our digits has nothing to do with Islam.
The Wikipedia entry of "Mathematics in medieval Islam" is a good place to look for a small sample of those contributions.
but I'am not talking about Islam my point is how are the Muslims scholar contribute to the science. and Islam has never been incompatible with modern science, and if you have time you can read more about Islam and modern science or if you want I can refer you to several website speak and give more details about.
What on earth gave you the impression that I ever thought anything different?
I have studied Islam, as well as the other world religions. I know that Islam as a religion is quite friendly with science, despite what some creationists (like this guy: /watch?v=L9R0XI2G3s4 ) seam to think.
I simply pointed out a very common misunderstanding about the Arabic numbers.

@greyman000 U R right....numbers which we call arabic are not actually arabic they are first used by Indians who introduced them....I am Indian and I am proud of it......now coming to Islam.....In Quran you can see many scientific fact which are now recently discovered......so Its true religion and I am proud to be a Muslim....
i've been studying in this area for 2 years and i have never seen a destinction between between orthognality and perpendicularity clearly delinineated--thanks sal!
Tank yoo verry much!! We did this a little while ago in da maths and i never really understood it but now you've just reinforced what i was taught and it makes perfect sense. You are a great teacher, keep it up!
i like the way he pronounces the word "perpendicular"

@afroze4all What has any god to do with math? As you said math was invented by people. Why mix religion in everything when it's fine on its own?

Religion has nothing to do with mathematics. There are no politics in mathematics.
