Great to hear that. Maybe I can do a series of videos on why bones break and how they heal (dedicated to you of course!). Actually, that's a pretty good idea. Need to do the basic bio first to do the healing part.
Thank you Sal. I work in an orthopaedic office and everyday I send all the kids that come in, to your website. The moms and dads come back to thank me for the info. When I talk to the kids I ask them how their math is in school and they look at me and say, "well I passed!" and then there's a chuckle. I've become a hit for them because they leave with more than a cast.
If only I had learnt from you Sir. I would have feared maths less and be fascinated by its beauty more. I now understand why some people's eyes have a glint when they talk about maths. Thank you for your contribution.
Wow just realized this video is over 12 years old.... and thanks to this over-a-decade old video I for the first time finally understand those conic figures at the end. They always looked so complicated but I finally understand it now!
Thanks for the relations between them. I'm looking forward for the different equations for the ellipse.... parameter.... polar.... etc. and how they relate to each other. You have the gift.
wonderful explanation, I am programmer, and maths always attracts me, and i was rusty and checking what i studied 21 yrs ago, and wallah this explanation is clear, and i re-learned the things today. Thank you for such wonderful lesson.
Your comparison of the two dimensional plain representing a single cross section of a three dimensional object completely just changed my picture of geometry, thank you.
Thank you so much. You can not understand how greatly thankful I am to for you, you're what we need in front of our classrooms and at our dining tables teaching kids things. Just, thank you.
Sal you really are amazing... I mean I'm sure there are some guys out there who do reasearch into things and work out complicated stuff but I'm not sure they understand things like you do.... and definately do not present or explain things as well...
Thank you for this. I'm trying to learn the topics I missed in High School to prepare for college this fall. Is this in a playlist yet? Which playlist would it be? Conics or precalc?
Oh you're too kind. It would be a neat idea and I'm quite certain some first year ortho resident would find it most appreciative to see this on You Tube as well as the kids who go on your website to learn how bones heal as well as break. I think you explained Wolf's Law in one of your physics videos.
Sir I like your video the way u do explain and make us understand, as a student I want to give you an suggestion please don't take it other way sir I thik your videos could be more clearly understandable if you add animations to it to explain concepts like conic sections and it would be ease for u too also to explain.😊
@weurRTG Thanks, I'm 17, in Quebec we learn this in the equivalent of I don't know how it works, somewhere in high school maybe, and it think it's really hard.
What if you put the plane completely vertical and in the centre of the cone? Is the result of that an absolute value graph...or am I just confusing myself now? Nice video btw! :)
I guess you never heard of Khan Academy,just search for khanacademy on google and visit their website and browse through the entire collection of video lectures.
YES!!!!!!! The canadian education system skipped THE ENTIRE CONIC SECTION on PURPOSE!!! and the SAT math II REQUIRES CONICS!!!!!!!!!!!! THANKS!!!!!!!!!!!!!!!!!!!!!!!!!!
@SOLOVEFUCKINGmuz Algebra II is usually taught at age 15, or 10th grade. However, I've seen 11th grade students take the course, and I've even seen 8th graders take the course. I took it as a 9th grade student.
Sir I have a question: wasn't that parabola one intersecting the above cone (the one which was parallel ) so won't it will actually become a hyperbola?
Ok I'm just thinking isn't a parabola and a hyperbola kind of impossible because if the cone goes on forever then you can't actually create that cut that they have right because they would just form an ellipse right? If someone can enlighten me so it actually makes sense or else I think we are doing this whole thing wrong right?
"you don't do this in your algebra 2 class" I am actually using this video for a project in my algebra 2 class where we are doing exactly what you said we shouldn't XD
The canadian/british education system just skip few stuff because the math class in combined, instead of having geometry,algebra... we only have one class where we are suppose to learn as much as content from both courses in the same time. The text books contains content (but it still skipped geometry). The teacher/school just doesn't teach it or leave it until higher levels. We learn probability/statistic in grade 12 and we will never learn things like conic, inequality & algebra longdivision
Everyone from Teague and Anderson, this is pretty good stuff! Better hope we don't end up chasing this down with 8 sections of notes though. XD Have a great day everyone! #p.4 teauge? nah #'s too lame Baylife
KHANic sections.
XD, you beat me to it.
Areeb Shahjahan beat both of you by two years!
You stole my joke
I just come here with the sole intention of making that joke

Still trying to work out how to arrange the plane and the cone to get that.
you're an amazing teacher! thank you for your time, sounds like you truly have a passion for teaching :D
this video is older than me and i still learned loads thanks man
Dude you are amazing. If everyone learned math like this, we would have a world of geniuses. Thank :)
It's one part talent and one part that he cares.
A rare combination. Far too rare.

Thank you Sir! I graduated high school with your help!! Thankyouu
I like the approach he does!
thx huge help for my class
Everytime i open one of your videos, i learn something new... that is the joy of watching your videoz, Thank you Sal
Sal you really are amazing... I mean I'm sure there are some guys out there who do reasearch into things and work out complicated stuff but I'm not sure they understand things like you do.... and definately do not present or explain things as well...
Thank you khan academy
I wish I had you as a teacher, your brilliant
You are amazing.🤓
Thank you for this. I'm trying to learn the topics I missed in High School to prepare for college this fall. Is this in a playlist yet? Which playlist would it be? Conics or precalc?
your drawings are amazing
thanks for doing what you do; mathematics is fascinating
most excellent! good explanation.

I would never pass without you Sal, thank you very much!!!!!!!!
Thanks for the idea!
My favourite of all your videos so far. very well explained indeed
ATTACK OF THE COLORED LINES!!
At 2:30 you have a smiley face lol
+aaron flores It is a tilted parabola. You are funny
Spanish Beard awww
hahahahaha this made me laugh
Why does noone reply to any of the comments below?
I actually fell asleep your voice is so soothing.
Still helpful for an old video and this is better than all the math videos from 2006 and 2007.
thank you

Dude the best channel !!! 1000×better than byjus
Awsm teaching
The funnest thing is i'm in pre-algebra and now i know and can look into the future :]
Thank you for this video. I am taking precalculus in college. It really helps. Thanks again, Sal Khan, Khan Academy
Thanks keep up the good work sir
Thank you!!!!! Now that I have watched your videos I understand all of it!!!! I use your website too. :D
Im currently learning this through BYU. this is much better
Dude this video is still useful even after 10 years of when it was published
11
12
What if you put the plane completely vertical and in the centre of the cone? Is the result of that an absolute value graph...or am I just confusing myself now?
Nice video btw! :)
really great introduction :)
Awesome video, very clear understanding at the end of it's ten minutes. Audio quality was superb.
Very cool, orbits are great.
Thats so true, but i still understand it all... once the jargon is outta the way..
well you learn something new everyday :)
I guess you never heard of Khan Academy,just search for khanacademy on google and visit their website and browse through the entire collection of video lectures.
Thank you :)
Great introduction
I learned alot
thank u sir for excellent lecture
Yes, there really ought to be a cool 3D software that shows all this more clearly.
Write down an outline for your video, will help with guessing what to explain next.
subtitled in 21 different languges. wow good job 👍
Reviewing conics for central force :3
Can u link previous videos please also using all maths on khan webpage how long is that going to take as takeb 5 days and only learnt 20 skills
The line and point are both conic sections as well, yes?
pioneering e learning!
That video was amazing! Great job Sal
thnx good explanation
12 years ago but I need this experience now
lol
Thankyou
i learn more from this channel than i do from my school teacher
I like your humor khan academy :))
Check this out! This video has a Download button in the description !!!
My teachers motto this semester:
Learn it yourself I am being fired for DUI!
Joy.
Thanks to you I learned conics and logarithms
YES!!!!!!!
The canadian education system skipped THE ENTIRE CONIC SECTION on PURPOSE!!! and the SAT math II REQUIRES CONICS!!!!!!!!!!!!
THANKS!!!!!!!!!!!!!!!!!!!!!!!!!!
@SOLOVEFUCKINGmuz Algebra II is usually taught at age 15, or 10th grade. However, I've seen 11th grade students take the course, and I've even seen 8th graders take the course.
I took it as a 9th grade student.
Whats wrong with the website??? On UA-cam I have to search for each video of a Chapter individually!
The parabola should've been drawn as a line in the planar view, not a curve, since the plan you're cutting with is perpendicular to the plan view.
yeah, correct! us too.
So is a point a conics section... if your plane is horizontal right in the point that the two tips of the cones meet?
Sir I have a question: wasn't that parabola one intersecting the above cone (the one which was parallel ) so won't it will actually become a hyperbola?
+Netra raman You're just viewing it wrong. If it's parallel, it will never cross.
Oh and one other thing, maybe you can use Google SketchUp it's a 3-D tool that's free.
Kind regards,
pongman
I love you sir.
just wondering in what year of studies do we learn that, the age I mean, trying to compare with quebec.
4:20
smiley face :)

Wow, this was before khan academy was even a thing, this was the beginnings when sal was alone, ig that's why the software and video quality is low
Is it Post at 14yrs Ago....
Now I'm less likely to fail my test. I literally made a 0 on a quiz to to a lack of understanding
"you don't do this in your algebra 2 class"
I am actually using this video for a project in my algebra 2 class where we are doing exactly what you said we shouldn't XD
Unquestionably World's best teacher!
Cap
Haha, 4:17 there's a smily face :)

do you use a drawing pad on making these or just ur mouse
Hey the formulas for parabola are not y = x^2 and x = y^2.....But they are x^2 = 4ay and y^2 = 4ax.....
+tuhin Dey Well, if I had to comment, yeah it looks right
taking precalc II trying to read ahead is this the same content that would be taught in my class? anyone have an idea?
Plexxar yea it's calculus technically, but usually Precalc 1 and Precalc 2 are required before you take calc 1
Thanks thanks thanks
Everyone from Teague and Anderson, this is pretty good stuff! Better hope we don't end up chasing this down with 8 sections of notes though. XD Have a great day everyone!
#p.4 teauge? nah #'s too lame
Baylife
How can I contact Salman ?
define focus?
Prrrrraabola!!
Exercise in 3-d drawing!! :D XD
Are you the same guy that does videos on other topics(e.g. vectors)? This one was terrible, I grasped nothing. But the other videos you're brilliant
+Tiisetso Mashele Yes he is!
not 100% attention !!!!
