11 - Graphing Points in 3D & Intro to 3D Functions (3D Coordinates - XYZ System)

In this lesson, you will learn how to plot points in 3d space using X, Y, and Z coordinates. We will show how to draw XYZ coordinate axes and how to correctly draw points in 3D space. We will then show how a function can be drawn in a 3D graph using a 3D function (a function of two variables X and Y).

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.

[felixyongco]

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.

Finally, I understood 3-D plot and I can related with statisitcs and other math 3-D graph.

You're an incredible teacher, Thank you for posting and making these.

[ivanaranda]

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

Great explanations and I finally understand this concept!

[exotickhanaarif]

One of the best professors I have ever seen.

[lucitamaldonado]

Thank you, it's been years since I've done this study that I for it. You made it easy to remember.

[georgettebeulah]

This make so much sense and meaning I can relate to it and really understand its meaning and get what your saying and mean.

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.

[junasub]

point (3, 4, 5) was incorrectly plotted around 24:10 in the video!

[arielbanzuela]

very gratefull i learned so much from you. you are a treasure.

[tagbro]

Very very 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 😃😃😃☺☺☺🤗🤗🤗🤗😇😇😊😊

[amethqal]

Thank you very much I operate CNC machine which moves in x, y and z directions now I can understand the 3d blueprint better

[GorVala]

Awsome video, thank you for sharing and all of the effort in creating superb content.

[raymondallenjhangiani]

Awesome ! Explanation, thank you ! 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[abdulwasaye]

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 👨‍🏫

[tacticolfire]

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 😏

[fouziasiddique]

Very well explained!
May Allah bless you!

[samuelcampbell]

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
