Spherical Coordinates 3D Animation

[@Lexyvil]

I don't understand why they don't teach this today at my university without using animations like these to help us visualize 3D shapes mentally. We have the technology now...

[@XYZandRGB]

I feel the same way. I made this because I couldn't find something similar. Most of your professors learned it from chalkboard drawings, so don't be too upset if they try to teach you the same way :)

[@tommygstonymec]

@@XYZandRGBhow do you go about animating things like this ?

[@XYZandRGB]

@@tommygstonymec I use Blender. I build all of the pieces you see in the video and vary their rotation and size and position using keyframes.

[@satwiknagulapati9377]

hmm

[@ryemiranda6800]

Maybe in the future generations they will use now animation or graphical representations using new technologies

[@broken_but_blessed]

A good teacher is one who can make complicated topics the most easiest ones. Thank you

[@wonbpoly]

Thank you so much, something stuck in my mind for more than 4 hours about this because the teacher at my university just talk about this for 5 minutes then solve 2 problems in 10 minutes so I do not understand enough but you know what not just me but also other students in my class but at the end they are still able to get 9 or even 10 at the exam, but I believe that not many of them know clearly about this, that is so sad about education when someone does not fully understand something and can get a 10 grade but others have to mine and understand deeply which costs a lot of time but in God I trust, the time I spend for math is not worthless. THANK YOU SO MUCH FOR YOUR LECTURE. God blessed you.

[@XYZandRGB]

@@wonbpoly Once you start to apply this knowledge, you will see the benefit of truly understanding the concepts, and will be helping your peers.

Thank's a ton for the animation man, it really helped, like fr. My prof isn't the best, she runs through the material like she's tryna speedrun the class

θ is to reduce the aggregate of three-dimensional space to a surface, Φ is to reduce the aggregate of a surface to a line, which is the intersection of the surface and the cone, and ρ is to reduce a line to a point. The positioning of any point in space can be completed.

[@koala1578]

Sending you all the best wishes, being able to explain difficult concepts easily is what marks a great educator. Thank you!

[@Shockload]

I have never understood the spherical φ coordinate and how it only goes to π and not 2π until i watched this video, THANKS A LOT

[@AK-zz7sn]

Animations help a LOT. This video made the concept crystal clear to me. Thank you!

[@funnyboy7603]

ty for everything, my friend saw your video and he say he gonna take 5 in the impossible test tomorow, god bless him and all the students

[@RajkumarDarbar]

finally I understood why the phi angle is between 0 to 180 degree in the spherical coordinate system. thank you sooooo much !!

[@abdullahrafeq6733]

i have a re-exam and now phi is much more intuitive than the first time!! Thanks very very much for such a good explanation!!!!

[@vinamrasinha6210]

Great video. Cleared all my doubts. Thank you so much for this! 😁

[@steveying1305]

This video made me understand why theta is only from 0 to π, thanks!

[@yasmeenajan3955]

this is marvelous effort to teach coordinates.

[@maheshnerlekar9791]

understood in a very easy way ...because you took lot of hard pain to do it. thanks a lot

Good luck on your exam!

[@vidyagandhimathinathan]

I actually appreciate your time, I had finally learnt.

[@ANJA-mj1to]

This was very concise! Illustrated fantastici! All important key features in order to calculate the transmitted irradience by angular dependent. Using Yours - presented coordinates and the following spherical coordinate system I can specify a given direction for the zenith and azimuth angles thus the transmittance of this system is a function of direction of incident radiation. So valuable information also for the irradience from the sun, sky and for all hemispheric areas given by the independent of changes in the sun or sky radiance. Thank you because performing an integration of the transmitted irradience and calculating the total radiant flux in civil engineering we can see better geometry for example water, glass, polarized elements, i. c. Also we can imply two-dimensional Fourier transform of Cartesian coordinates if we understand better first important step that implys in all disciplines not only engineering approach! 👏👏👏👏

Thank you very much. It might have took some effort to make this video, I am grateful for this.

[@miltonvento8767]

Thanks so much for making this video. Unique and super helpful visualization!

[@commonwombat-h6r]

thank you SO MUCH for this video. It got me unstuck. I didn't realize that the vertical angle goes only from 0 to Pi, not to 2Pi, like angles usually would

[@malefetsanekoalane4549]

Great animation.Thanks. You have my subscription. I think greatly of all the pre computer graphics mathematicians who could see it all in their heads.Makes one wonder? In the long run are our brains going to be less or more capable of visualisation?

[@XYZandRGB]

That's such an interesting question. I feel like we are adding to the number of people that can visualize a topic each time we express it in a new way. There's no shortage of difficult concepts to understand, so I suppose anyone can still exercise the skill as much as they want. I had a colleague suggest that some boys gain an advantage in spatial visualization over girls from jumping off of playground equipment and tracking movements of the ball in sports more often. I have no idea if nature or nurture is the main culprit, but I suspect it's a skill that can be strengthened.

[@malefetsanekoalane4549]

did you mix up phi and theta? my notes and other videos show them the other way

[@korlagoutham3659]

Awesome explaination

[@culturecreating]

as in polar coordinate 2d we needed an initial line and pole for frame of reference , i wonder if we need all the three axes here?

[@XYZandRGB]

Changing the frame of reference from what I described here is a bit more advanced than what I can cover here, but I would assume we need all 3 axes to define a frame of reference.

[@nakshatrasharma7183]

Can't theta be from π/2 to 3π/2 at 5:25 or it is same as π to 2π

[@RahulSharma-oc2qd]

theta is positive when it is measured counterclockwise rotation from x axis about z axis. I guess that might be the reason for it being in the range of π to 2π.

[@XYZandRGB]

Remember that theta starts at the positive x-axis, just like polar coordinates. It's a little odd because it "looks" like it is starting on the left.

wonderful

[@subhadip3679]

5:50 can anyone explain why phi is not from pi to 3/2 pi

[@XYZandRGB]

phi is measured from the top of the z axis. phi = 0 is the positive z-axis, and phi = pi is the negative z axis.

[@subhadip3679]

@@XYZandRGB i understand that, but if you consider anticlockwise it will go from pi to 3/2 pi and if you consider clockwise it will go from pi/2 to pi. i wonder if its correct both ways.

[@XYZandRGB]

@@subhadip3679 The range of phi is defined as being from 0 to pi, so those are the only valid numbers for phi. Are you sure we're not talking about theta?

[@saari0103]

5:24 why theta limits are from pi to 2pi Could you pls explain

[@XYZandRGB]

Theta starts at the positive x axis, and moves toward the positive y axis, so it has to travel halfway around and start at pi.

Great video

[@onarollthough7380]

So x and y axioms have an angular relationship and the z axioms phi is independent, having half the values because its the same on either side of the axis without concern with position. Hmm interesting stuff.

fi will be with x axis not theta

Your textbook may label them differently. This is how they are labelled in Stewart's Calculus.

[@ssm-56281]

[@Brekstahkid]

Wow, this helped a lot. Thank you

[@gerard-nagle]

great animations, can I ask how they were created?

[@XYZandRGB]

I made them using Blender, a free 3D software

[@micahfullinfaw]

I need these animations! my prof's drawings are so hard to interpret

[@MandeepSingh-ge3fu]

Is fie not clockwise?

[@XYZandRGB]

"fie" or phi originates from the positive z-axis, and it travels in all directions. To use an analogy, 11:00 and 1:00 on the clock would have the same phi value of 1 hour

[@dodserdar958]

cylindrical polar coordinates when parallel to x-axis how can i solve something like this???

[@XYZandRGB]

I would think about how you can redefine your variables. Instead of theta being related to x and y, have it related to y and z.

[@jlpsinde]

Very good

[@taladasandeep8497]

The question is when do we use normal triple integral(dz dy dz), triple integral in cylindrical coordinates (r dz dr dθ) or triple integral in spherical coordinates? is it based on the graph or there is a better way of knowing this ""Given that sometimes we encounter functions that are hard to graph

[@XYZandRGB]

I would suggest using the coordinate system that has the most constants in its bounds. You can convert the equation you are integrating to any coordinate system you like, so it is usually based on the shape of the solid.
