its nice to see the 3d rotation and representation of these quadric surfaces rather than on a 2d page. i salute you sir thank you

[@waisybabu]

Thanks! This series on Quadric Surfaces is helping a lot in my Calculus-II course! Keep it up!

[@sealgirl922]

This video really helped clear some things up for me! Thank you!!

[@derekminear320]

Great video. My textbook does a TERRIBLE job explaining this but you nailed it. Keep it up, man.

[@edgarpoe7901]

Thanks man great video. The characteristics list for each was extremely helpful.

[@loopuleasa]

Okay, you really know how to explain fun concepts.

[@DetectiveMcGarnacle]

Thank you so very much for this and all your videos

[@jordanperez8055]

Great videos, thank you so much!

[@bundeligafan]

excellent presentation, thanks a lot

[@ethantsai8611]

which plane is the third plane when you talk about hyperboloid of 2 sheets and eliptical cone?

[@droitnow]

This is soooooooooo helpful :) thanks a lot :)

[@hazelnutspice]

Hi, do you have a link to that powerpoint/slideshow you are presenting in that video?

[@hecz250]

Excellent video (and much needed reminder at the end). However, shouldn't the paraboloids have a z/c rather than z/c^2 ?

[@Mathispower4u]

Hector Nevarez Yes, I annotated the correction. I apologize for the typo. Thank you for notifying me.

[@jerryji6254]

Thanks for a great video!
Are the course materials (slides, 3D renderings or so) uploaded? If so, where should I download them?

[@zajec11]

great video, but can you give me any applications to these surfaces?

[@VamshiKrishnaThandu]

which software did u use to draw the graphs

[@randhawa153]

Thku sir it helped me alot👍👍👍

[@ramizhossain9082]

Beautiful.😊

[@csutherland9]

in elliptical paraboloids and hyperbolic paraboloids shouldnt it just be 'z/c' not 'z/c^2'?

[@flame19931rs]

thanks for the help

[@djslife7082]

Great job, this was very helpful

[@Mathispower4u]

Thank you for taking the time to leave a comment. I appreciate it. I am glad you found the lesson helpful.

[@silvereye731]

found this a day before a calc 3 exam. indispensable.

[@Mathispower4u]

Yes, you are correct. However this would be considered a degenerate hyperbola because degenerated to two lines or asymptotes

[@Mugwump720]

I have a question about the "Elliptical Cone" when we set y = 0, don't we get the equation x^2/a^2 = z^2/c^2? Then don't we also get z = + or - sqrt(x^2 * c^2 / a^2 ) ? Which would equation z = + or - (x * c / a) which would be a two lines and not a hyperbola right?

[@charlesAcmen]

i agree with you from 13years later

[@meryemcemileerol]

Thank you so much❤

[@laurenbauer1548]

what software are you using to graph these functions?

[@nicklindsay-abaire9782]

two years late but it looks like Maple

[@udayand2695]

Thank you sir❤

[@napluto2031]

Great, thanks a lot

[@unknown827]

can you define surfaces please? i don't understand what that is :(

[@dominioninside2233]

Many thanks

Where are the other subsequent videos on quadric surfaces?

very usefull

The Elliptic Paraboloid equation should be z/c=(x^2/a^2)+(y^2/b^2). The c should not be squared.

[@Mathispower4u]

rosalinda0210 Yes, I annotated the correction. I apologize for the typo. Thank you for notifying me.

[@genpeng]

@vthandu556 looks like maple

[@irizhg]

Maple

thankss...my chinese professor sucks the hell out of us...

[@leizhang3329]

nice!
