How to Differentiate Cross Product?

AI Thread Summary
To differentiate the cross product of vectors U and B, the discussion references the equations dB/ds = -TN and dU/ds = KN, along with the relationship N = U x B. The key to deriving the equation dN/ds = TB - KU lies in applying the product rule, specifically the Leibniz rule, to the cross product. The original poster confirms they have solved the equation, indicating that the differentiation process was successful. The conversation emphasizes the importance of understanding the product rule in vector calculus.

Hi all,


I have a qustion.

dB/ds= -TN, dU/ds= KN (1)
N= U x B (2)


dN/ds=TB-KU (3)

How Eq.(3) can be obtained from Eq.(1),(2)?


Have a nice day!

just like any other product. leibniz rule.
 
Thank you,

I solved the equation. Thank you!
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
