Very clear English, very knowledgeable, and man he is so passionate to make his students not only LEARN by head but by heart. I personally thank Professor John ..I have done my math studies more than 60 years ago.. and I like it.. I liked his COLORED pencil. We do not have COLORED pencil before except white CHALK.
Hey, the explanation is good but there's a mistake in plotting point Z in 3-D. The height from the origin to z-axis must be equal to the height from x-axis to z-direction. However in your explanation it is exceeding and marking the point wrong. Please rectify this as a lot of people are learning from your videos. Thanks.
Very very veryyyyyyyyyyyyy Thank you so much !! You are great !! You Solve my easily !! Many a days I'm confused how i can plot ? how i can understand 3D by visualization ?? ....etc you solve my problem easily & Again Thanks a lot very much 😃😃😃☺☺☺🤗🤗🤗🤗😇😇😊😊
The only problem is that on the Z axis, how are you supposed to be precise? I see from z to y you count specifically (example, (2,5,3) you go to 2 on z, 5 to the right where it lines up with 5 on y, but when going to z, it doesn't seem to count up correctly
In this video he graphs the z wrong AF. The zero point for z should start at the xy intersection and count up from that spot. He explains it correctly but then he draws it as tho the z is counted up from the point 0, 0 on the x y axis, which is completely wrong (unless the x and y actually are both 0) and looks weird.
@@chaoticrampage7946 right! My teacher made us do the normal grid, but with an extra line influencing the 2nd (positive,positive) and 3rd (negative,negative)and intersects through (0,0). this new line will now be x, the line that used to be x is now y, and the line that should have been y is now z.
This is a very good teacher but at 30:10 both of the Z axis measurements are a little off. Better look at a couple more videos on this before you think you know how this works.
Thanks Roy. I know how it works :) I am drawing by hand and the drawing isn't to scale. I think I got the point across though, which was to show how a function of two variables is plotted on a 3D graph. I am not a computer as I am drawing by hand - thanks and good luck in your studies. Jason
Jason, if you look at timestamp 30:10 you have the only video that does not show a 3D box. This is the first video I saw on 3D graphing and I had to find other videos to learn how this works. I have more respect for you than you know but I think this time you should take a closer look at what I'm saying. It needs to be corrected. But if not then OK. I still love you :) and I'll say thank you very much for the lessons on Sin & Cos. 👍✌
I just saw one without the box, Professor Leonard. He showed a diagonal line from (0,0,0) to the corner of the square on the (X,Y) plane. Then on the Z axis at the measurement drawing a line parallel to the new diagonal reference line. Then a vertical line.
I think the plotting of (3,4,5 ) is wrong. The plotting won't be on 5 on the z axis since its moves downward 2 units below the y axis so it'll only move 3 units in the z axis . Thanks. I think you have to make this correction
I just wonder why x and y directions are not the same as in the classical x, y coordinate system, and y is named z ? Would it matter much if x were named z instead ?
man, you explain things better than any professor i've ever had; so glad I found you when I am about to start my masters.

So nice of you!
You're an incredible teacher, Thank you for posting and making these.
One of the best professors I have ever seen.
Great explanations and I finally understand this concept!
You not only save me through Intro to Statistics but I got an A. Now I am starting calculus 3 and I need a refresher on all these vectors basics
point (3,4,5) was incorrectly plotted around 24:10 in the video!
No it wasn’t. It’s correct. Please look again.
@@MathAndScience the segment joining (0,0,0) and (3,4,0) and the segment joining (0,0,5) and (3,4,5) seems not parallel
Done subscribing your you tube channel today!
Thank you, it's been years since I've done this study that I for it. You made it easy to remember.
Finally, I understood 3-D plot and I can related with statisitcs and other math 3-D graph.
Very amazing explanation.
Thanks teacher!we love you!!
very gratefull i learned so much from you. you are a treasure.

I agree.
This make so much sense and meaning I can relate to it and really understand its meaning and get what your saying and mean.
Thank you so much!
Now I realized how stupid our teachers were. They are lazy and never put energy in classroom and also very dumb. Man you are true teacher 👨🏫
Great explaination, thanks sir 🙏
I love math
Very very veryyyyyyyyyyyyy Thank you so much !! You are great !! You Solve my easily !! Many a days I'm confused how i can plot ? how i can understand 3D by visualization ?? ....etc you solve my problem easily & Again Thanks a lot very much 😃😃😃☺☺☺🤗🤗🤗🤗😇😇😊😊
Thank you very much I operate CNC machine which moves in x ,y and z directions now I can understand the 3d blueprint better
Great Work. Thanks for sharing!
I really appreciate it!

I think...function in this particular lesson means... Indicator or reflector of how much the temperature at exact points, determined by x and y value.
I see what he's doing here, just like Goku did vs Majin buu. He starts in the first form all the way till even beyond 😏
Awesome ! Explanation , thank you ! 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Awsome video, thank you for sharing and all of the effort in creating superb content.
Very well explained!
May Allah bless you!
الله يهديك للاسلام ❤❤thanks very much

It does not add up. I looked at some other videos and found out why. He made a mistake on this one for sure.
Your plot of (3,4,5) in the Z-direction is absolutely wrong😢. Please make another video to correct the error
Please upload your lecture on quantum physics
Great job
THANK YOU... SIR...!!!
How to apply the XYZ axis to the pipe?
Actually, the temperature in your first example is also a function of x and y because the metal bar is a 3D object !
This is a very good teacher but at 30:10 both of the Z axis measurements are a little off. Better look at a couple more videos on this before you think you know how this works.

@@roysmith3198 Yes you don't need any box to graph in 3D - it is optional - I chose not to show box. You just need the x, y, and z axis.
You great man 👍👍👍👍👍
Sir, on (3;4;5) the point 5 on exactly on 5 at the z plane. Recheck please
bruh all the Minecrafters knows Y suppose to be upwards
thank you for such a great video btw!

Point too high at 24:10, should be lowered according to XY negative offset.
Great sir
Location to Los Angeles to Boston and Tennessee.
Which course is this video part of?
engnrng
Thanks sir
Thanks for the video, hoping that you would tackle the cylindrical and spherical method
Yeah that is more in the realm of calculus 3. I'll do more lessons on those systems in the future!
Thank u sir
hello z value is not correct. You need to count from where the parallelogram meet.
I just wonder why x and y directions are not the same as in the classical x, y coordinate system, and y is named z ?
Would it matter much if x were named z instead ?
It also bothers me but than I remember that The US still uses Imperial system even though it also doesn't make any sense
Good jop 👍👍
Thanks so much!
EEEEEEAZZZZY,I AM ONLY IN 4th GRADE AND I KNOW THIS
Your a year older now, go watch it again and see if you can catch the mistake this time. It's very bad. Hint: it involves the Z axis.
epic
ZZZZZZZZZ
Thanks sir
