Why is dB/ds a scalar multiple of N? How to get the definition of the torsion? Calculus 3

[@ianfowler9340]

Very nice. Brings back memories of my undergraduate physics courses. It is so nice that these 3 mutually perpendicular vectors come together to have such great applications in the physics of motion. Well done.

Yes, I tutored calc/ODE/linear/etc. for 10 years a few decades ago. Calc 3 was always my favorite. Been a subscriber for a couple years. Look forward to your take on calc 3

Thanks for teaching us calculus 3 , i was waiting it for a long time ❤😅

What does the constant magnitude of B have to do with the orthogonality between dB/ds and B?

Lovely ❤

Are you made vedios about vectors before? Because i don't understand them well 😅

[@bprpcalculusbasics]

@@conanedojawa4538 I haven’t done videos on just vectors. Is there anything in particular you would like to know?

Thank you, for showing me that torsion requires more thought than the textbook implies. IK∆e

I thought B had to do with magnetic fields. I have no clue as to what B and N refer.😢
