Why the hell physicists have to disagree with mathematicians? 😆 I'm a physics student and I agree with the mathematician's version cause that's what we learn in polar coordinate before getting into spherical version.

@mrmeowtv62486 жыл бұрын
I like theta much more for the angle between the projection of the vector onto x,y plane and the positive x axis because it is what we are used to for all of the math before Calculus III before introducing the z axis (when dealing with the (x,y) plane). It is easier to remember for me, but that's mostly a matter of personal preference.

I was reading through the second edition of "Introduction to Electrodynamics" by Griffiths, and found the conversions (p. 45), but couldn't really understand them, as no derivation was shown; however now that i watched your video its crystal clear. Thanks! Sometimes when you don't understand something (e.g. a derivation, or a result) the best thing to do, is try it out yourself.. (but couldn't since i was travelling in a bus).. Danke!

Something I had a realllly hard time with in E&Mwas reminding myself that this is all trying to describe something that's real. I had to work towards not just looking at it as one math problem after another, and start asking myself what I would expect the solutions to look like and if they made sense physically. Asymptotic behavior goes a long way!
@notadestinygun65566 жыл бұрын
Andrew Dotson exactly what my Professor informed me. He said stop looking at these problems algebraically but more from a geometric perspective. That it’s important to justify the answer.

The notation used in this video is the dominant one (not just in physics but also in engineering) while the notation used in most North American calculus texts is almost never used beyond Calc III. That means anyone planning to take advanced math courses should be following this video, regardless of field of specialization.

Thanks. Very helpful. Until now, I’ve always thought of x=r sin theta times cos theta as meaning ...r sin theta tell you the degree to which cos theta is maximized. As if r sin theta is like a potentiometer working on cos theta. If r sin theta is zero then cos theta is minimized. If r sin theta is 1 then cos theta is a full sin theta.

@AndrewDotsonvideos6 жыл бұрын
It's annoying. You really can just switch theta and phi, but it just gets confusing when reading a calc book, and then doing something like E&M where it's switched. Newton totally would have called one theta_1 and the other theta_2 lol
