Physics Ch 67.1 Advanced E&M: Review Vectors (75 of 113) Spherical Coordinates: What is theta-hat?

[@valeriereid2337]

This is a very brilliant explanation. I especially like it that you always show every step so there is no confusion, no wondering where things came from. This helps us to understand better. Thank you. You're the best Professor.

[@MichelvanBiezen]

Yes, I used to hate it when our professors skipped steps and I couldn't figure out the missing steps.

When you say chapter 67 are you referring to a book? Or is it just a way of listing your videos ?

[@MichelvanBiezen]

This is just the order of our videos.

Your teaching method is excellent.Hope to be your student sir. ❤

[@MichelvanBiezen]

Thank you. Glad you found our videos. 🙂

Hello, what's the reasoning behind using partial derivatives to find the unit vector? Also, why did we need the unit vector to find the surface area of a sphere?

[@CatsBirds2010]

I like both methods that you have shown. This method compliments the other one.

[@MichelvanBiezen]

Great to hear!

[@leelanagasrinivasarao2515]

Sir do some more videos on tensor calculus

[@MichelvanBiezen]

Not yet. That is for the future.

[@jameyatesmauriat6116]

Thank you Sir. Is this one step to deriving the Laplacian in spherical coordinates?

[@MichelvanBiezen]

Sorry, but we didn't understand your question.

[@essaadanibadia1095]

Thank you professor

[@MichelvanBiezen]

You are very welcome

[@marty4486]

Hello professor. Maybe you're interested in getting your videos captioned? Do you have a business email?

Hello sir i have question in the pulley related (Mechanical reasoning)

We try to answer questions when time permits

@@MichelvanBiezen try to connect me this time i ask the question

[@MichelvanBiezen]

Many viewers ask questions via these comments. Better to start a question on a new video, as these comment move done far quickly with all the viewer comments.

[@salmanahamadansari7425]

Ok,i put my question on the video there were my i confused to understand.

[@emilywong4601]

I learned this method in calculus 3 in community college (lower division), so why is this "advanced"?

[@budtastic1224]

Application of higher level math IS advanced

That is why the playlist is called: "review vectors". There are a number of topics covered in this playlist that are not covered in calculus courses, such that this will give a good review and understanding of the material. We constantly review so that we can solidify our understanding
