When you spend years in university paying people to teach stuff to you but you still end up learning everything for free in 10mins YT videos. This man is the best teacher I have ever seen, thank you so so much.
@@MichelvanBiezen Thank you :) I really meant it, cylindrical and spherical coords were notions I could not understand, from classes and even other videos. You are the only one that managed to make me actually fully understand it, the world would be much smarter if every teacher were like you :))
My wife and I put many many thousands of hours of hard work into these videos (over 9000 by now) and we really appreciate the "pat on the bac" from our viewers like you.
there are a lot of countries in which not everybody is allowed attend university and study. These videos are extremely valuable resources for people who want to learn more although for them is forbidden. I really appreciate your job. I can say , your lessons are distributed among young people with cds and dvds for whom doesn't have internet access.Thank you sir
My textbook glosses over this with the words, "In cylindrical coordinates, (x-hat,y-hat, z-hat) can be expressed via the following equations in cylindrical coordinates: [then it states the two equations you derived and continues] They are the inverse transformations of of equations [then it sates one ones you started with]." It's so much more satisfying to see where these equations come from instead of the too often hand-waving in my book. Thanks so much!
It's fantastic. Thank you so much! This is really helpful. In our lecture only forms were given without deduction. I have thought so hard why unit vector different as coordinates, and which direction p und phi actually point at. I have looked up online for answers but most are not so clear. Thanks again! You are life saver, teacher!
I noticed (rhohat, phihat) are a rotation of (xhat, yhat) by an angle phi, so the inverse transformation comes out to be a rotation in the other direction! Thank you always for the lectures.
Hi Michel, can you please explain, in the context of Faraday's law, if uniform magnetic field passes through a coil of wire and you want to calculate the curl in cylindrical coordinate system, you'd need the components in the s, phi and z direction. Why does s and z component have zero electric field while, phi has a non-zero one.
When we have charged distributions of various shapes, such as cylinders and spheres, it is easier to calculate the voltage and electric fields using cylindrical and spherical coordinates.
Hello sir, The angle phi from phi= -sinphi(x direction) + cos(phi)y direction is the same as the one from ro = cosphi(x direction) + sinphi(ydirection)? if so , how do we know that ?
Do you line these videos up with classes you may teach yourself? Because I always find all your videos to be extremely relevant to my current course material. lol
+Austin Some of the videos do line up with the classes I teach to help my students understand the material better. Other topics I cover because of requests I have received from the viewers.
If you put this in matrix form you will notice that the inverse matrix ( or transformation from one to another coordinate sistem) is the transpose of the starting matrix.

We appreciate your comment. 😃

We are glad to read that these videos are reaching those who do not have access to the internet or a university. Thanks for sharing.
@Jupiter Tanha: You remind me one of my friend from a middle eastern country who was denied higher education because of her religion.🙏

Made my day!. My college professor (so called) is like a newborn in front of you.God bless you with good health and life.Thank you😊😊
I am now in my MSc. and this is probably the clearest explanation I have ever heard! #dope

一样的感觉hhh

Thank you so much. You are brilliant at what you do.
Thank you. Glad you find our videos helpful. 🙂

Thank you very much . Can I know what are the nature of questions that come about these equations and if we have to memorize these in some cases ?

@@MichelvanBiezen Do you please have questions about them for examples related to Electromagnetics ?
This video was really helpful
Thank you sir🙂
This is amazing !!! What a Beautiful lecture !!!

You are awesome, thank you for sharing your knowledge:)
My pleasure! Glad you find the videos helpful. 🙂
Thank you so much for this great explanation, you are the best doctor :)
Thank you Sir. You are awesome!
Thank you so much for this video! Everything was explained clearly!
Even IITian's understand from his lectures ❤
Sir why the sin(phi)xhat is negative in phihat = -sin(phi)xhat + cos(phi)yhat? aren't we in quadrant 1? so x component should be a positive sign?
thank you very much its very helpful
Thank you so much!!
thank you sir!
Yeah
Rock on
