Let me know if i am doing wrong.. thanks in advance

I don't know ! :confused: what is \frac{\partial r}{\partial z} I did following : \frac {\partial \frac {z}{r^3}}{\partial z} = \frac {1 * r^3 - z * \frac {\partial r^3}{\partial z}}{(r^3)^2} = \frac {1}{r^3} - \frac {z \frac {(\partial r^3)}{\partial z}}{r^6} where \frac...

yes Tiny-tim, actual answer is \frac{\partial (z/r^3)}{\partial z } = \frac{1}{r^3} - \frac{3z^2}{r^5} tiny-tim, as you told me i did partial differentiation using quotient rule and chain rule and i got \frac{\partial (z/r^3)}{\partial z } = 1/(r^3) - (3z)/r^4 \frac{\partial r}{\partial...

Thank you tiny-tim, after doing partial differentiation and chain rule i got following. d (z/r^3)/dz = 1/[r][/3] - 3z/[x^4] * dr/dz but actual answer is 1/[r^3] - 3z^2/[x^5]

Mathematical method in electrical potential ?? Hi All, I need mathematical help from the topic electrical potential for lectures on physics by Richard Feynman. Need some help to understand mathematical method used here. question : 1) From electrical potential.png ( how this partial...

Hi Bill_k, Thanks for reply but what that means ? "conjugate to a particular coordinate"... physical intrepretation

what is the difference between canonical and conjugate momentum.. ? what is its physical significant.. I was reading classical mechanics by Goldstein but could understood this terms
