  • thank you, my math teacher just babbles and she gets her self confused most of the time, then i lose focus. basically your a lot better than my math teacher

  • so that equation is for ellipse because it has different coefficient. right?

  • you and Stephan Colbert saved my life

  • I have an analysis final tomorrow. Needless to say, thanks so much.

  • good good

  • Dude your videos are by far the best on Youtube.

  • woot thank you man

  • what about the parabolas,ellipses,hyperbolas that have a straight line as its axes...not the x or y axes

  • YOU HERO. I have to teach myself 2 semesters of stuff and this is helping

  • This videos are great thanks to all teachers that make this videos... God bless you all!

  • Thanks for all your effort. I did my schooling from suburban India. Although being a design engineer, i had some aversion over certain areas of maths. But your teaching created love on maths & physics. All youngsters should get this kind of class education. Thanks for being so nice... God bless you sal!!!!!

  • Great videos!! Thanks Sal

  • Intresting!!!

  • This is very useful to me. Thank you.

  • amazingly i understood it.....lol

    i am 14 years old btw

  • hey Sal I have a question, do you have any tips if you get some "tricky problems" in a math class in which you think are impossible.

  • a cretionist would argue that order can't come from chaos but you'veproved them wrong lol!

  • MY BRAIN IS GOING TO EXPLODE!!! I'll stick with polynomials for now, thanks.

  • You're the best.

  • Very Nice!!

  • YOUR VIDEOS ARE AWESOME!

  • Nice Khan!, Do you do LSAT logic?

  • For motivation: examples for uses in day to day life for all these conic things. At least mentioned.

  • To be honest, very few people need to know about conic sections for their day-to-day life. They are really useful if you're studying planetary motion or trying to send a probe to jupiter. They are also interesting in and of themselves.

    If I were in charge of the school system, I would cover statistics in more depth instead of conic sections. Much more useful.

  • I agree. Statistics is it. Doing Math for doing math is good for brain training. And a trained brain can be useful.

    So - more statistic videos, Sal.

  • @khanacademy

    In that case you must hurry up and become in charge of the school system!

    thanks for the videos!

  • @khanacademy definitely agree

  • SICK VIDEO

  • awesome vid
