As x is more than 0, that means that the parabloid isn't flattened, but as it is less than 1, it becomes smaller (the outputs), so therefore, all values of z decrease. Hence, my answer is b
Just want to say that your formatting is really well designed and the course plan will run smoother through this type of visualization. Another victory for the education revolution.
In every x-y plane we get a circle and the radius depends on the value of z where z = f(x,y). Is this parabola actually a change of circle over time/radius plotted on z-axis?
I really find your video very very helping. Can you do a video of scalar functions in three variables. More importantly, visualising scalar functions in different coordinates systems.
Pease help...can I please know which mathematical animation software is used in these videos ...its amazing ...please let me know if anyone knows...thanks
His current videos in his own channel do use all his own code. This video looks like his own virtual blackboard, but the 3D plot in the middle is done with the graphing calculator that comes with Mac OS X (Applications/Utilities/Grapher)
I would also recommend Mathematica highly as vis and math software. Very worth learning imo. And student or amateur licenses are super cheap (and often free if in uni).
Would this give the same output as the integral from 0 to infinity of x^2 rotated around the y-axis or is it coincidental that they look almost identical?
Really long time ago but .... the graph looks exactly like x² rotated around the y axis. But the integral would give the area under the curve of x² and with your bounds .... only the right half. Could be wrong though im just a calc student like the rest of us. ( calc 3 now)
Do you guys know any good textbook/book that follows the flow of this course (entire playlist on multivariable course)? I want to use it as an additional material, also to solve some exercises from it. Thanks :)
What graphing software do you use? I cannot afford any professional programs, but I absolutely LOVE graphing. For 2D graphs, I use Desmos, but I haven't been able to find a decent 3D graphing software, which can keep up with my crazy functions. Thanks!
Im modmaker fore one game (shadow fight 2) i need to output the data from the file responsible for the model to this graph and then edit it how to do it

James Smith point out a spot in the air with your finger. That can be represented by a three-dimensional point, with a of the corner of your room being the origin
This guy is lying. If you have a three dimensional graph of an equation, it will give you a line/graph, nonetheless, not a 3D shape. I would know: I'm a game production major (in 3D, animation) and a former physics major. But, nobody will care, mostly because this probably didn't deserve any purpose, to my knowledge.
Dude you didn't include the context of different dimensional inputs. You refer to a 2 dimensional input, (x,y), to give a 2d shape, which you are right on, but when the third variable z is another input to the multivariable function, the cone like 3d parabola he showed was true. Also keep in mind you may be confused with vectors and in Calculus you need to remember that surfaces and areas can have fluctuating values. For example a rational function may have some weird oscillations and so the area under is measured by lim h->infinity of the riemann sum of the approximations under the curve.
@@startuckval5198 Nice try!! But, you're the only one confused about anything, not me. Give it a rest. I know what a graph looks like, 2D or 3D. I don't make mistakes when it comes to this stuff.

Yes.
Yes
...and yes.

This is great! The graphical illustrations help me visualize the function! I've never seen this subject taught like this! 🎉😊❤
This series is to 3blue1brown as Tim Robinson's 'The Characters' 1/2 hour is to 'I Think You Should Leave'

Thank you so much
"shloops" used in a perfect context xD
thanks for making this video.

We need a simple video that goes from basic common core all the way through to differential equations. Maybe an hour or so lol
how did your year go from the time you posted your comment to now?
great video
Thanks
Very nice..May which are the tools you have used to create this content?
excuse me, can i know what software did you use for that 3d graphic in your video?
thank you for help before :)
I would like to know as well!
@Jorge Ávila Balmaceda thanks
He is using the macOS preinstalled "Grapher" App

you could put as many axis in the xy plane as you want
Can we make this using projector sheets??
I am just curious, if we were to create a formula to create a 4D parabola, would it be:
f(x,y,z,) = x^2 + y^2 + z^2
?
most probably
Marvellous💯
Explained well!♥️♥️🔥🙌🙌
Which application was used to graph these functions tho,plz i need a answer guys
Can we think of multivariablr functions as dot product like 2 dimension getting scaled to one dimension
This is not math, this is art.
yeah, that's why it's useless
I clicked on khan academy i'm sure not 3b1b

Gabriel Barbosa u can use the text UCSB math 6a/6b which is about vector calculus
i love this video
So the partial derivative only shows a change in Z because x or y, (depending on whose partial derivative you take) will be constant?
can a function mapping from 3 dimensions to 2 dimensions be fit into 3 dimensions ?
ty!!!
this is awesome
You're amazing!

I wish you taught at Rutgers
What program can I use as a 3D graphing calculator?
GeoGebra but if you have a Mac computer you can use Grapher.
Can anybody suggest me app for android and software for windows.
From which I make make this 3-D graphs?

Excellent videos… What software do you use to plot 3d functions?
he is using the in-built grapher on macOS

Try Geogebra, you can graph 2D- and 3D function with it.
How can I graph such functions in my phone?
Making curves, drawing tangents, rotating graphs, bla bla?
use online graphical websites like geogebra 3d or apps like "math lab graphing calculator for android"
@@rezarxy thank you a very much!
what software are you using

Am I the only one who thought they were the first to think about graphing a 3d function only to be disappointed learning it already existed😂

Though his analogies are useful, I find the way he explains things convoluted and sometimes confusing.
