You're really a great professor. Sometimes the videos are long, but every time i finish one I always understand the concept so much better! (I'm a conceptual person, I have to learn the concept before doing the math. You are GREAT at explaining concepts.) :]
This one reminded me of Grant's (3 blue1brown) topology video in which he maps pairs of ordered points on a loop onto a surface and then onto a torus. Loving this course.
I think the same , the three variables can specify any point in a space but two variable can specify any surface in a space and 1 variable can specify any curve in a space
Surely you are joking Mr. Khan! 270 degrees = 3 pi/2 in leu of stated 3 pi/4 Thanks for all the great insights. I'm very grateful for your help on my budget :0)
Khan I love you for your lessons they are awesome! But please, please, PLEASE fix the 3pi over 4. It's 3pi over 2 and I've seen it in another video too and it pisses me off, I don't know why, but it does! FIX IT!
13 years, still appreciating the hard work Sal puts in his videos, and especially his drawing skills
finally... the world has a math teacher.
Thanks for helping with my last minute finals studying. Also I believe it should be (3pi/2) on both the S and T axis at about 9:40 rather than (3pi/4)
i'd like to stop for a moment and appreciate how good the hand drawn illustrations are.
@Frinniz you're right. Sorry about that.
how did the response comment get down here? Let's help it :=D
This was posted before comments where nested. There was no "REPLY" button back then.

I think it should be 3pi/2, not 3pi/4 on your graph. :D
yeah.. that's why I just moved to the comment section to see what others think..
I didn't notice. It was at 3 quarters so 3/4*2π=3π/2, he forgot that 2.
Yea that's right
exactly！
To visualise easier, check out this video at 5:34
Well, that was neat as heck.

I found this video very interesting but I can't find the sequel to it.
Has it just not been uploaded yet?
Thank you
thank you sir for visulazing the graph !!! and for easy explnation
Bro you are actually a god thank you hope you are doing well 12 years later 💀
thats the best looking hand drawn doughnut i've ever seen
please make videos on differential geometry like fundamental forms of surface
I can't find words for how thankful I am. 🙏🙏
Thanks for the great visualisation!
Where can I find the full playlist for the old version?
thank you very much!
I understand it more! thank you!
I saw doushnut before doughnut xD
but thank you Khan
mathematical recipe for making doughnuts :D
Thank you Sal
Starting to comprehend. Thank you.
Excelent video. Excelent class.
Great video. Thank you!
I always thought that it just meant it continues on to infinity, like when we first learned about lines you put an arrow on both ends
Amazing sir
yay, i love yeti doughnuts! thanks sal!
nice explanation sir
Great explanation, but it is 3*pi/2, not 3*pi/4 :)
Why put extra arrows on the axes in opposite directions? Doesn't an arrow mean that there is an increase in that direction?
Cool video
What's the difference between a parameter and a variable?
I think the same , the three variables can specify any point in a space but two variable can specify any surface in a space and 1 variable can specify any curve in a space

people make mistakes, man :)
I'm 3 years late, but don't use big words if you don't know how to use them :p
Would you please tell me that in which university you take classe and give this illustrious lectures?
I just want to point out that you say 3pi/4 a few times in this video, when you mean 3pi/2. Otherwise, you're doing a great job.
really good explained sal ;)
Samuel Khan, you make a mistake, it should be labeled 3pi/2 , not 3pi/4 on the axis at 9 minutes and 40 seconds into the video.
lol its salman khan
also the areas shaded are not matching with top view figure.
Yeah I caught taht 3pi/4. I bet he was think of 3/4 of one revolution. Good to know even this guy makes mistakes.
bad to know... we are less perfect than we want to :(
to bad patrick didnt make a video about this...
Is the angle s, the angle between the x-z plane or the x-y plane?
this is very late but s is the angle between the radius line (in the video denoted a) and the x-y plane
Why isnt b considered also a parameter?
You lost me at green donut
at 18:10 you are shading the wrong part!
I like pie 8-}
Khan I love you for your lessons they are awesome! But please, please, PLEASE fix the 3pi over 4. It's 3pi over 2 and I've seen it in another video too and it pisses me off, I don't know why, but it does! FIX IT!
Best
you say zy axis all the time, dont you mean the zy plane?
Homer Simpson: mmmm Torus :)
It really bothered me that he didn't close the left-hand side of his donut all the way....
Is it not 3pi/2 and 3pi/4? That was annoying me the whole time.
What the he11 is a doughnut?
you know it as "donut"
doushnut
I can learn anything: including how to fail this class
:D
:x
may i borrow your brain?
