Wouldn't proj_n(u) be denoted u_n for the normal component of u? I thought u-hat should be reserved for the unit vector that points in the same direction as u
fan of brazil I do the Faculty of Mathematics. I love your classes (videos) Could you make a video about Unsolved Analysis math problems yet? (I used google translator to write)
faster way to have determined the length of the projection is [ [ u dot n ] / mag [ n ]^2 ]* vector n = [ [ u dot n ] / mag ( n ) ] * (unit vector n ) . So the magnitude of the projection is nothing but the value multiplying the unit vector which is ( u dot n ) / mag ( n ).
WTF = want to find
or what the Fermatica
Jajajajajajajjajajajajjaja jajajajajajjajajaja WTF
I kinda like this proof a lot in wiki. Very glad to have you make a video of it !
u made my day. My search ends here. thank you gentleman.
Your video helped a lot, and you were very funny. Thank you
11:38 - Result is hurting my eyes!
Yeaah Dr Peyam, delicioso bocadillo matemático bajo en calorías...
Thanks! Dr. P, we need Overviews of: Multicalculus, Probability theory and Statistics!
thank you very much!!!

Love Calculus
That's good; but this is vector geometry; no calculus was involved.

@@ffggddss Thanks for the correction, Fred :)
Hey - I love calculus, too! ;-)
Fred
"In terms of fingers" is the best thing to hear in a mathematically rigorous argument
Excellent video, Dr Peyammmm. Please make integration videos with change of variables, greetings from Argentina .
Already done ✅ Check our my videos on the Jacobian
I'll look at it, thank you.
Hello Dr. Peyam :) can you make a video on graphing cylinders and surfaces?
fan of brazil
I do the Faculty of Mathematics.
I love your classes (videos)
Could you make a video about Unsolved Analysis math problems yet?
(I used google translator to write)
More analytic geometry please :D
Video request: could you prove that orthocenters, circumcenters, centroid and Longchamps point exist on a spherical triangle? Thanks!
Oh my God thank you
DR PEYYYAAAAAAM
is the whiteboard slightly tilted?
Haha, no, the whiteboard is straight, but the camera angle is a bit tilted, that’s why!
faster way to have determined the length of the projection is [ [ u dot n ] / mag [ n ]^2 ]* vector n = [ [ u dot n ] / mag ( n ) ] * (unit vector n ) . So the magnitude of the projection is nothing but the value multiplying the unit vector which is ( u dot n ) / mag ( n ).
nice!
Congrats on your midterm, you did well 🙂
thanks a lot,see you on monday😃
Multivariable calculus makes me happy. Weird I know :)
It’s a beautiful subject, actually! :)
Good; but this was vector algebra. No calculus involved; although the result can find use in calculus.
Fred
I should have learned by now; a comment section on the internet is no place for subtlety ;)
what about the distance between a 2D-line and a point ?
Almost exactly the same :)
Upload complete videos lecturers of mathematics for graduate and postgraduate level including Mechanics.
This is basically the same with a point and line just with two coordinates instead of 3.
3/√108------>>1/√12
= 1/(2√3) = ⅙√3
Two other ways to write it.
Fred
@@ffggddss Yeah I calculated both of those. Just thought one of the three was the more proper simplest form.
Yeah, yours is good, and each of those has its merits. I was just giving more possibilities.
Fred
Hello!
You are less than three
Peyam
Hahaha awwww ❤️
What is wtf lmao
Want to find lol
