Cartesian, Polar, Cylindrical, and Spherical Coordinates

[@CuongVu-kg9qo]

This video definitely save me. I'm now studying in an university in Vietnam, this is what i learned yesterday in my first physics class, and it was terrible, I completely didn't understand any word my lecturer said until now i found your video. Thank u so much

[@mohammadghaziasgar3160]

I am lost for words to say thank you, I always had issues for different coordinates and confused, now I get it totally. love you from Iran

[@BeniSnow]

AE501: I'm so impressed by your dedication to making the videos on fairly dry topics as engaging as possible. Love the pvc pipe and cardboard props!

[@ChristopherLum]

Beni, thanks for the feedback. I try to keep it as interesting as possible. My favorite prop is the dog 😁

[@muhandez6484]

calculus is dry for those who dont fully understand it

[@keyshawnb4845]

AE 501: I will definitely reference this video in the future! Well made and easy to follow when translating to cylindrical, polar, or spherical coordinates.

[@hshams28]

AE501: Really great walkthrough of the coordinate systems, I think it really helps to draw them out (or use props as you did) to get a "feel" for where a point really is; this ends up actually making it really easy to understand the different coordinate systems and how they relate to one another!

[@sethwhittington28]

AE501: Fantastic review of coordinate systems. I didn't feel lost during this lecture at all, yet still felt like I was learning. Perfectly balanced lecture!

[@ChristopherLum]

Seth, I'm glad it was helpful, thanks for the feedback!

[@kabandajamilu9036]

The world's best teacher nice explanation

[@NK-iy6if]

Who ever is trying to find atan2(x,y) using a casio calculator, good news you can! Just type shift + on your calculator, then pol( will apear on the screen after that type in your x value, then press shift ) which will type in a comma then type in your y value after the comma and close the brackets, this will give you both the r value and the theta value. Thank God I was able to find this way, and I hope that it helps you. All praise to God the most high!

[@augustinematthew2055]

Thank you

@ you’re very welcome, glad the method helped

It has been a while since I touched on how each coordinate system connects to one another. Awesome content, thank you!

[@gandhodithippeswamy1579]

Your lecture is so good. From your lecture I got clear idea in which subject spherical coordinates notation is perfect. Thank you so much.

[@ryoonoue1076]

AE501. It's pretty easy to get polar coordinates mixed up so I'm glad you've made this video to review. Thanks for the vid Professor

[@tranpham7120]

AE501: Pretty much clear. Thanks professor for this video.

I love your use of props! Very helpful and illustrative.

[@robertdelossantos1936]

This did an excellent job explaining how spherical coordinates are reached. Hopefully this sticks, but glad to have it as a reference.

[@markmurphy5374]

Also good discussion at the end about typical conversions from Cartesian to Spherical as I've seen it done that way many times but good to have the proper inverse tangent there.

[@Sam-b9x6k]

36:55 The constraints on phi are giving me some trouble. Won't -pi/2 to pi/2 just cover the positive z axis, i.e. the points starting from the x-y planes and going up in the positive z direction. Would we be able to describe points in the negative z hemisphere if we were to apply these constraints? To me 0 to pi makes sense. -pi/2 to pi/2 is giving some trouble. Can anyone please explain?

Lot of thanks, 👏.Could you explain the look angles (azimuth and elevation) from a point (for example, a satellite) and the transformation if these into cartesian coordinates? Thanks in advance👍.

[@ChristopherLum]

Can you provide more information? Are you looking for how to translate between the different coordinate systems?

[@manusego]

@@ChristopherLum Exactely. I would like to know how to translate the position of a satellite orbiting the Earth expressed by the coordinates [Azimuth, Elevation] into the rectangular coordinates [x(t), y(t), z(t)]. Thanks in advance teacher. 👍

[@gordonlim2322]

35:21 Coordinates in polar/cylindrical/spherical are not unique

[@notatoyotacamry195]

Hey! This was a wonderful explanation, and I didn't even know about four-quadrant functions! That said, when it comes to transforming from Cartesian to spherical, does it not work the same if you eliminated the sqrt(x^2 + y^2) and the sqrt(x^2 + y^2 + z^2) denominators? Since this is a common factor of both components, I think atan2 will still produce the same angle.

[@ayouboularbi9681]

sir how is cos(pi/2 - phi) = sin(phi) instead of -sin(phi) well we know that cos(pi/2 - theta) = cos(pi/2).cos(theta) - sin(pi/2).sin(theta) that gives us 0.cos(theta) - (1.sin(theta)) which equals minus sin(theta) -sin(theta . that's confusing haha)

[@tharun_017]

Sorry but that's a wrong formula you're using to check it The right one is Cos (A - B) = (Cos A • Cos B) +(Sin A • Sin B)
