How to Differentiate Cross Product?

Click For Summary

Discussion Overview

The discussion revolves around the differentiation of a cross product in the context of a mathematical problem involving equations related to magnetic fields and forces. Participants are exploring how to derive one equation from others using differentiation rules.

Discussion Character

  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant presents a set of equations and asks how to derive a specific equation from them.
  • Another participant suggests using the product rule for differentiation.
  • Further responses indicate that the Leibniz rule applies, implying that the differentiation process is similar to that of other products.
  • A later reply mentions that the original poster has solved the equation, but does not clarify the method used.

Areas of Agreement / Disagreement

Participants generally agree on the applicability of the product rule and Leibniz rule for differentiation, but the specific steps to derive the equation remain unclear and unresolved.

Contextual Notes

The discussion does not provide detailed assumptions or definitions related to the equations, and the steps leading to the solution are not fully articulated.

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!
